You may see the above error if you are using the SQL server Destination in your SSIS package.

Sql server Destination cannot be used in packages that access a SQL Server database on a remote server. Instead use the OLEDB destination.

Things to note for SQL Server Destination

a. It offers the same speed as the Bulk Insert Operation.
b. It does not support Error Output.

Problem with SQL Server numeric data : Error converting data type varchar to numeric.

Vivek — Tue, 08 Sep 2009 18:23:58 +0000

Today I stuck with an interesting problem of converting number data in Varchar fields to numeric datatypes. I have created the following sample data

Create table SQL script

The data in the table contains Decimal and scientific values in varchar format as shown in the figure below.

Now when I tried to convert the above values to numeric as below it returns only 3 rows but with the following message

Wrong SQL

Msg 8114, Level 16, State 5, Line 2
Error converting data type varchar to numeric.

The isnumeric does return 1 for all the 4 values in the table. I modified the query so that it initially converts to
float and then converts to numeric and it works.

Correct SQL

The conversion of a char data type to a datetime data type resulted in an out-of-range datetime value

Vivek — Mon, 22 Jun 2009 11:53:02 +0000

The Error Occurs when the input is date and the given day values are not in the range of the expected days for a given month(1-31)

For eg.

You cannot specify the date parameter as Feb 31 2009 since february only has 28 days in a non-Leap year and it throws the above error.

Null value is eliminated by an aggregate or other SET operation

Vivek — Mon, 06 Apr 2009 14:11:09 +0000

The Problem occurs when an aggregate function(max,sum,avg..) exists on null values. Trying to get rid of the null values may be the solution but in certain cases..you may need the extra data relying on the null values.

So whats the solution?
Append set ANSI_WARNINGS OFF on the beginning of the sql statement.

When using the same in SSIS packages the Packages may fail.The Output Window may indicate that there is already a OLEDB destination exported which in this case is the error message.

An OLE DB record is available. Source: “Microsoft SQL Native Client” Hresult: 0x00040EDA Description: “Warning: Null value is eliminated by an aggregate or other SET operation.”

So use set ANSI_WARNINGS OFF

“Set identity_insert on” errors for more than one table

Vivek — Tue, 24 Feb 2009 16:55:27 +0000

I was trying to remove the Identity inserts for 4 tables all at once but I keeping getting errors like Cannot remove the Identity insert on table 2 as the table1 already has identity insert on.

So after digging into the MSDN I was surprised to see the following lines

“At any time, only one table in a session can have the IDENTITY_INSERT property set to ON. If a table already has this property set to ON, and a SET IDENTITY_INSERT ON statement is issued for another table, Microsoft® SQL Server™ returns an error message that states SET IDENTITY_INSERT is already ON and reports the table it is set ON for.”
