The options can come from use of the SET command or from the sp_configure user options value.]] The Transact-SQL programming language provides several SET statements that change the current session handling of specific information. The SET statements are grouped into the categories shown in the following table. For information about setting local variables with the SET statement, see SET @local_variable Transact-SQL.For application programs other than REXX, the default values for the options are specified on the CRTSQLxxx command. Each option is then updated as it is encountered within a SET OPTION statement. All SET OPTION statements must precede any other embedded SQL statements. At the start of a REXX procedure the options are set to their default value.Option 1 The @@LANGUAGE Configuration Function. To find out how, see How to Set the Current Language in SQL Server T-SQL.

Specifies that the indicated query hint should be used throughout the entire query.Each query hint can be specified only one time, although multiple query hints are permitted.Only one OPTION clause can be specified with the statement.

SQL Server provides us with a number of options to control SQL Server behavior on the connection level.These session-level options are configured using the SET T-SQL command that change the option value for the session on which the SET command is executed.Changing the default value of these session-level configuration affects how the session queries will be executed affecting the query result.
The performed change on a session-level option will be applied to the current session until its value is reset or until the current user’s session is terminated.In this article series, we will list nine most common and heavily used session-level SET options and how SQL Server behaves before and after changing its default configuration.In this article, the first in a two-part series, we will describe the first four options. The ANSI_NULLS session-level option, as the name indicates, controls if the SQL Server Database Engine will follow the ANSI SQL Server standard in prohibiting the usage of the equality operators to compare with the NULL value, as the NULL is never equal to anything.Instead of the equality operators, the IS NULL and IS NOT NULL can be used to compare the current value with the NULL value regardless of the current ANSI_NULLS option value.The T-SQL syntax that is used to control the ANSI_NULLS option is shown below: SET ANSI_NULLS When setting ANSI_NULLS to ON, all comparisons against the NULL value will evaluate UNKNOWN; the (column_name=NULL) and (column_name NULL) in the WHERE clause will return no rows even there are NULL and non-NULL values in that column, with no mean of using the equality operators to compare with the NULL value.
Setting the ANSI_NULLS to OFF, the Equals (=) and Not Equal To () comparison operators will not follow the ISO standard for the current session and can be used to compare with the NULL value.In this case, the (column_name=NULL) in the WHERE statement will return all rows with NULL value in that column, and the (column_name NULL) will exclude the rows that have NULL value in that column, considering the NULL as a valid value for comparison.Take into consideration that, for executing distributed queries or creating or changing indexes on computed columns or indexed views, the SET ANSI_NULLS should be set to ON. Otherwise, the operation will fail and the SQL Server will return an error that lists all SET options that violate the required values.The SET ANSI_NULLS setting will be set at run time and not at parse time. We will create a simple table and insert four records into that table: In addition, we will see how the SQL Server behaves by default, when using the equality operators to compare the table values with the NULL value, and how it differs from using the IS NULL and IS NOT NULL operators: The result will show us that, no result will be returned when using the equality operators in evaluating the NULL values, which means that, by default, SQL Server evaluates the NULL value to UNKNOWN and will not consider it as a normal value that can be compared using the equality operators.This is not the case for the result returned from SELECT queries that use IS NULL and IS NOT NULL to evaluate the NULL values, which return correct values, as shown in the result below: Setting the ANSI_NULL option to ON then executing the same SELECT statements: You will see clearly that the NULL value is comparable now using equality operators; where the Equal to (=) operator works same as IS NULL operator and returns all rows with name column values equal to NULL.
On the other hand, the Not Equal to () operators works same as IS NOT NULL operator and returns all rows with name column values not equal to NULL, evaluating the NULL value as any other normal value, as shown in the result below: It is better to use the IS NULL and IS NOT NULL operators for the NULL value comparison that will work in all cases regardless of the ANSI_NULLS option setting.The ANSI_PADDING setting controls how trailing spaces are handled in columns with CHAR and VARCHAR data types, and trailing zeroes in columns with BINARY and VARBINARY data types.In other words, it specifies how the column stores the values shorter than the column defined size for that data types. Vantage fx binary options platform providers. The T-SQL syntax that is used to control the ANSI_ PADDING option is shown below: SET ANSI_PADDING When the ANSI_ PADDING option is set to ON, which is the default setting: The SET ANSI_PADDING option is always ON for the columns with nchar, nvarchar, ntext, text, image data types.Which means that trailing spaces and zeros are not trimmed from the original value.The SET ANSI_PADDING option affects only newly created columns.
