To prevent the error, you can use one of the following alternatives: For example: SELECT * FROM TestPermTab AS a INNER JOIN #TestTempTab on a.Col1 = #TestTempTab.Col1 īecause tempdb uses the default server collation and TestPermTab.Col1 uses a different collation, SQL Server returns this error: "Cannot resolve collation conflict between 'Latin1_General_CI_AS_KS_WS' and 'Estonian_CS_AS' in equal to operation." With the previous example, the tempdb database uses the Latin1_General_CS_AS collation, and TestDB and TestTab.Col1 use the Estonian_CS_AS collation. ![]() Create a temporary table with the same column declarationsĬREATE TABLE #TestTempTab (PrimaryKey int PRIMARY KEY, Col1 nchar ) In this system, the tempdb database uses the Latin1_General_CS_AS collation with code page 1252, and TestDB and TestPermTab.Col1 use the Estonian_CS_AS collation with code page 1257. For example, an instance of SQL Server uses the Latin1_General_CS_AS collation and you execute the following statements: CREATE DATABASE TestDB COLLATE Estonian_CS_AS ĬREATE TABLE TestPermTab (PrimaryKey int PRIMARY KEY, Col1 nchar ) ![]() This could lead to problems with a mismatch in collations between user-defined databases and system database objects. This means that all implicit columns in temporary tables and all coercible-default constants, variables, and parameters in temporary stored procedures have collations that are different from comparable objects created in permanent tables and stored procedures. All temporary stored procedures or temporary tables are created and stored in tempdb. If you create a user database and specify a different default collation than model, the user database has a different default collation than tempdb. This is typically the same as the default collation of the instance. The tempdb database is built every time SQL Server is started and has the same default collation as the model database. SQL Server implicitly converts the values to the collation of the column. You can insert or update values in a text column whose collation is different from the code page of the default collation of the database. When you work with tempdb, the COLLATE clause includes a database_default option to specify that a column in a temporary table uses the collation default of the current user database for the connection instead of the collation of tempdb.
