Use DB_Connect to Connect to Database
The DB_Connect and DB_Close instructions make it
easy to log into and out of the database.
The SQL_DBConnection variable is used with all the
other instructions to indicate which connection to use.

DB_CreatMapping to point to table and fields.
• Tablename is used to specify the table
• MapVar is the variable you want to send
• The Mapvar variable’s structure specifies the fields
The DB_CreateMapping instruction
specifies the database “table” to be
used, the variable to be mapped to the
fields, and if this vaiable is to be an
insert (_DBC_SQLTYPE_INSERT),
select (_DBC_SQLTYPE_SELECT),
update or delete.
Specify the table name
Create a variable for the data. The data
“type” is a structure that matches the
field names of the table. Up to 1000
fields.
You do not have to specify all the fields
in a table – just the ones you want to
use. The Select statement uses an
array variable for the multiple records
in the answer.
