Description
The RDO_CONNECT() function is used to connect to a data source. The numeric value returned should be saved to a variable to be used by other functions to reference the connection. Connection references start from 0 and correspond to the cursor/workarea -1. If RDO_CONNECT() returns -1, the connection failed.
| Keywords | Description |
|---|---|
| <expC1> | Servertype: "recital", "oracle", "db2", "mysql" or "postgres" |
| <expC2> | Hostname: IP address or character name |
| <expC3> | Username: account used to access the data source |
| <expC4> | Password: password for account above |
| <expC5> | Database: database to connect to |
Example
conn = rdo_connect("mysql","localhost", "user", "pass", "test") if conn > -1 rdo_exec("create table mytable (phrase char(20))", conn) rdo_exec("insert into mytable values ('Hello world')") echo rdo_affected_rows() rdo_close(conn) endif
