MS SQL: SQL Server supports enabling and disabling individual constraints such as the following.MS SQL: Supports Microsoft common language runtime (CLR) procedures, functions, and triggers.To drop a column default use the following: ALTER TABLE.ALTER COLUMN.DROP DEFAULT. Therefore, when creating a column default this way, the constraint name is ignored. Babelfish: PostgreSQL handles column defaults in a different manner than SQL Server does, and there is no constraint name associated with a column default.SQL Server also supports dropping the default using that same name. MS SQL: Supports creating a column default with an explicitly specified constraint name.If your SQL Server database is configured to be case-sensitive for identifiers, Babelfish will identify MyTable and MYTABLE as the same object. For example, the identifiers MyTable and MYTABLE refer to the same object. Babelfish: For PostgreSQL, only case-insensitive identifiers are supported.In this setting, MyTable and MYTABLE would identify two different objects. However, SQL Server can be configured so that identifiers are case-sensitive. So MyTable and MYTABLE reference the same object. MS SQL: By default, SQL Server is case-insensitive for identifiers.Babelfish: psql returns a generated column name.MS SQL sqlcmd returns a blank column name. sqlcmd and psql handle columns with blanks differently. This can happen when the column is an expression involving more than a table column reference and no column alias is specified. MS SQL: Allows column names to be blank when sending a result set to a client application.MS SQL: Microsoft SQL Server offers a command line utility called bcp as a common way of importing and exporting data.īlank column names when there is no column alias.Babelfish: Use backup tools as for standard PostgreSQL.MS SQL: Assembly modules and common language runtime (CLR) routines are not supported ( CREATE ASSEMBLY).MS SQL: Supports table hints, query hints, and join hints.MS SQL: sysdatabases.cmptlevel will always be NULL.SET COMPATIBILITY LEVEL will be accepted and ignored MS SQL: Backwards compatibility is set with COMPATIBILITY_LEVEL.Babelfish: This is currently not supported. ![]() ![]()
