Bulk Insert Task Failing On Data Type Conversion For A Destination Column Of Type Bit

Jul 6, 2006

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

Variable Data Type Help

Apr 10, 2006

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

Change Data Type Of Variable

Oct 3, 2007



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 !!

How To Use Value Of A Variable In Defining Data Type

Dec 14, 2007



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

Analysis :: Which Data Type To Use For Variable Values

Aug 19, 2015

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.

SSIS Custom Data Flow Component - Variable Type Converter

Jun 27, 2007

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;"

Compare Data-type Xml In A Temp/variable/physical Table In MSSQL 2000

May 22, 2008

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.

Server: Msg 279, Level 16, State 3, Line 12
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.
