View 1 RepliesHello Everyone,A have a Managed Stored Procedure ([Microsoft.SqlServer.SqlProcedure]). In it I would like to call a UserDefinedFunction:public static SqlInt32 IsGetSqlInt32Null(SqlDataReader dr, Int32 index) { if(dr.GetSqlValue(index) == null) return SqlInt32.Null; else return dr.GetSqlInt32(index) }I than allways get the following ErrorMessage:Column, parameter, or variable #1: Cannot find data type SqlDatareader.Is it not possibel to pass the SqlDatareader to a SqlFunction, do the reading there and return the result.My original Problem is, that datareader.GetSqlInt32(3) throws an error in case there is Null in the DB. I thought SqlInt32 would allow Null.Would appreciate any kind of help! Thanks

I am trying to use the Bulk Insert Task to load from a csv file. My final column is a bit that is nullable. My file is an ID column that is int, a date column that is mm/dd/yyy, then 20 columns that are real, and a final column that is bit. I've tried various combinations of codepage and datafiletype on my task component. When I have RAW with Char, I get the error included below. If I change to RAW/Native or codepage 1252, I don't have an issue with the bit; however, errors start generating on the ID and date columns.
I have tried various data type settings on my flat file connection, too. I have tried DT_BOOL and the integer datatypes. Nothing seems to work.
I hope someone can help me work through this.
Thanks in advance,
SK

Hi all,
I am trying to extract certain data from MySQL
(example sql statement is SELECT COLUMN1, COUNT(COLUMN2) FROM TABLE
GROUP BY COLUMN1) and stored COLUMN1 and COUNT(COLUMN2) values into
variables and then copy the values from the variables and insert them
into a new table in sql server 2005 and has two columns in it (COLUMN1
of type nvarchar and COLUMN2 of type int). I can map the first output
(COLUMN1) correctly to variable type String and store them in the new
table in sql server 2005 (store the value in a variable type String and
then use insert and store it into sql server using parameter in Execute
Sql Task set the data type to NVARCHAR, but I cannot map the second
output (COUNT(COLUMN2)) using the same method, I could not even get it
to store into a variable of any type. Anyone have any idea how to go
about it? Thanks in advance.
The output of the sql statement for MySQL should look like:
COLUMN1 COUNT(COLUMN2)
----------------------------------------
aaa 101
bbb 232
ccc 542

how to pass the numeric(12,0) data type to a variable in SSIS? what kind of variable data type should I choose?
I am trying to assign object_key column ( numeric(12,0)) to a variable in SSIS
If i select int32 , it keep giving me an error:
Error: 0xC001F009 at Row by Row process: The type of the value being assigned to variable "User::Object_Key" differs from the current variable type. Variables may not change type during execution. Variable types are strict, except for variables of type Object.
Is there anyway to change the data type of a variable while in an expression?
My problem is I am trying to compare a variable w/ a string data type to a variable w/ an object data type. I would change the data type of the variable from object to string but if I do that my sql task fails when it tries to write a value to that variable. The variable w/ the object data type is the result of an openquery sql stmnt. So I guess there are two ways around my problem.
1. Change data type of variable while in an expression..ie flow constriant
or
2. Change data type of vraiable from object to string and still get the openquery result to work.
Any help???
Thanks !!
HI Experts,
I have same table structures in two database and one master table which contains Table id, Table name,primary key, data type of primary key. i have to comapare
Tables in both tha database and as per result i have to do insert,update or delete.
for that i have written query :
DECLARE @rowcount_mastertable FLOAT
SET @rowcount_mastertable = (select count(*) from master_table)
DECLARE @TABLE_ID float,
@TABLE_NAME varchar (100),
@primary_key varchar (100),
@Primarykey_DATATYPE varchar (50),
DECLARE @COUNTER FLOAT
SET @COUNTER = 1
WHILE (@Counter <= @rowcount_mastertable)
Begin
SET @TABLE_NAME = (SELECT TABLE_NAME FROM MASTER_TABLE TABLE_ID = @COUNTER)
SET @primary_key = (SELECT primary_key FROM MASTER_TABLE WHERE TABLE_ID = @COUNTER)
SET @Primarykey_DATATYPE = (SELECT Primarykey_DATATYPE FROM MASTER_TABL WHERE TABLE_ID = @COUNTER)
--In below line i want to declare a variable and datatype should be same as what we got from master table so that i can use this @MAX_primary_key to fetch --max of primary key from table name where table id is 1
DECLARE @MAX_primary_key @Primarykey_DATATYPE
SELECT @MAX_primary_key = MAX(@primary_key) FROM @TABLE_NAME
WHERE TABLE_ID = @COUNTER
---But by running it i am getting error that "Incorrect syntax near '@Primarykey_DATATYPE'. and "Must declare the variable '@MAX_primary_key'.
Please suggest
Thanks in Advance
Greetings my SSIS friends
I am attempting to create an expression as follows:
"Select * from someTable where someColumn >= " + (dt_str, 25, 1252) @[User::DateTimeVariable]
The problem is that my variable is a Datetime field and when I convert it to string, the string will not execute correctly.
How to solve this problem?
Can we retrieve data from table type variable as an array in oracle key values..
E.g.
ALTER PROCEDURE prn1( @p_prn as KeyValuePair readonly)
-- proc which having parameter table type as parameter

declare @v_formatted_str varchar(50)
BEGIN
set @v_formatted_str = v_formatted_str + @p_prn(1)(1)
END
I am trying to find what datatype I can use for variable values like below in a column
E.g. column which we get
10000.10
100
180.34
98203710231.34
From the above example, you can see some of the values contains no decimal and with decimal
Also we cant say whether the decimal comes after the 5th number or 10th number. Any other datatype to capture this values. If not last option is to give varchar2.
how to pass the column that has a numeric(12,0) data type to user variable in SSIS? what kind of variable data type should I choose?
if i select int64, it keep giving me an error:
Error: 0xC001F009 at Row by Row process: The type of the value being assigned to variable "User:bject_Key" differs from the current variable type. Variables may not change type during execution. Variable types are strict, except for variables of type Object.
there is no numeric data type in variable..
if you click the drop down box in variable data type, you can only see the below data type:
Int32
int64
Object
Sbyte
single
string
uint32
uint64
boolean
byte
char
Hi all,
I am creating a customer data flow component for SSIS for use in a package. I've got some custom properties that I am exposing using the supplied advanced editor (no custom property editor here).
Some of my properties are enumerated types, and I have deciphered how to get those properties to show as dropdown lists of their respective enumerations. (For those of you who may be looking as hard as I did as to how to accomplish this, see the end of this post.)
I also have a few properties which request SSIS package variable names - such as an file name variable. However, I can't figure out how to tell the advanced editor that the property is looking for an SSIS variable, so that it can show a dropdown list of package variables, much like virtually any other Microsoft supplied Data Flow component can.
Is there a Type Converter I could specify for those custom properties? Is there another way to instruct SSIS that my custom property is expecting a variable? Or do I need to code a custom UI for editing my Data Flow Task?
To create a dropdown list of values for a custom property that represents an enum, do the following:
1. Create your enum definition, such as "public enum ThisIsMyEnum { one, two }"
2. Create a new class that inherits from TypeConverter, such as "public class MyEnumConverter : TypeConverter"
3. Override "CanConvertFrom", and return true if "sourceType == typeof(string)"
4. Override "CanConvertTo", and return true if "destinationType == typeof(string)"
5. Override "ConvertFrom", and return the enum value (such as "one" or "two" in my example) that corresponds to the string passed in the parameter "value"
6. Override "ConvertTo", and return a string that corresponds to the enum value passed in the parameter "value"
7. Override "GetStandardValuesSupported" and return true
8. Override "GetStandarValuesExclusive" and return true to indicate that ONLY the enum values should be accepted
9. Override "GetStandardValues", and return a new StandardValuesCollection constructed with Enum.GetValues() of your enum, such as "return new StandardValuesCollection(Enum.GetValues(typeof(ThisIsMyEnum)));"
10. Just above your "public enum" declaration, add a "TypeConverter" attribute to link your type converter to your enum, such as "[TypeConverter(typeof(MyEnumConverter))]"
11. In "ProvideComponentProperties", after you've created your custom property like this: "IDTSCustomProperty90 propEnum = ComponentMetaData.CustomPropertyCollection.New()", add another line to specify the TypeConverter property of the property to the full assembly name of your type converter, like so: "propEnum.TypeConverter = typeof(MyEnumConverter).AssemblyQualifiedName;"
Does abyone know how to compare data-type xml in a temp/variable/physical table in MSSQL 2000?
I tried this works in MSSQL 2005,
Code Snippet
create Table #t1 ([c1] int identity(1,1) not null, [c2] text)
create Table #t2 ([c1] int identity(1,1) not null, [c2] text)
Insert into #t1
Values('This is a test')
Insert into #t2
Values('This is a test')
Select * from #t1
Select * from #t2
Select * from #t1 where [c2] LIKE (Select [c2] from #t2)
drop table #t1
drop table #t2
but not MSSQL 2000.

The text, ntext, and image data types are invalid in this subquery or aggregate expression.
Is this true (from BOL)?
Code SnippetIn comparing these column values, if any of the columns to be compared are of type text, ntext, or image, FOR XML assumes that values are different (although they may be the same because Microsoft® SQL Server„¢ 2000 does not support comparing large objects); and elements are added to the result for each row selected.

Hi,
I'm trying to figure out the best way to determine the data_type of a column, given the table name and column name. Once I've determined it's a charactor string I can get the length using COL_LENGTH, but I can't fund a command or procedure that will return the data type.
Thank you.
How do I programatically change a column (say username) in a table (say tblusers) from varchar(25) to varchar(100)I am looking for something likealter tblusers set username as varchar(100) I know the above statement in nonsensical but it conveys the idea.

Does anyone know how to determine the base datatype of a column? I've tried using sp_columns but if there are user defined datatypes on the column it returns that name instead of the base datatype. I've also tries accessing systypes and syscolumns to determine the base datatypes.
Any tips or trick would really be apreciated!
