SQL LOCAL TIME TABLES (LTT)
SQL local temporary tables – unique in modules and built-in SQL programs in SQL sessions.
Syntax for DECLARE LOCAL TEMPORARY TABLE in SQL
DECLARE LOCAL TEMPORARY TABLE tab_name
( column_1 datatype [ NULL | NOT NULL ],
column_2 datatype [ NULL | NOT NULL ],
…
);
where:
- tab_name – The name of the local temporary table you want to create
- column_1, column_2 – The columns that you want to create in the local time table. Each column must have a data type. The column must be defined as NULL or NOT NULL, and if this value is left blank, the database takes NULL as its default value.
Example
Let’s look at the SQL example of DECLARE LOCAL TEMPORARY TABLE .
DECLARE LOCAL TEMPORARY TABLE suppls_temp
( suppl_id int NOT NULL,
suppl_name char(50) NOT NULL,
cont_name char(50)
);
This example will create a local suppls_temp time table.
