The SET statement.
See Teradata Vantage™ - SQL Stored Procedures and Embedded SQL , B035-1148 for details.
You can specify these options for assignment statements.
- A keyword introducing the SET statement used for assigning a value to a variable or parameter.
- You can assign a UDT expression to a UDT variable or parameter; however, the mutator SET clause syntax (see UPDATE in Teradata Vantage™ - SQL Data Manipulation Language, B035-1146 for details about mutator SET clause syntax) is not supported within a SET statement. The workaround for this is to use the standard non-mutator SET clause format, with the column reference on one side of the equal sign and a UDT expression containing the appropriate mutators on the other side.
- Name of the variable or parameter to be assigned a value.
- If you are assigning to a parameter, it cannot be an IN parameter.
- If you are assigning to any variable, it cannot be named QUERY_BAND.
- You cannot set values for status variables in SQL procedures.
- Arithmetic and string expressions that contain the value to be assigned to a variable.
- SQL procedure local variables, status variables, IN or INOUT parameters, and FOR loop column and correlation names can be specified in the assignment_source, which is also known as a value expression.
