Top Forums Shell Programming and Scripting How to pass value from plsql script to unix bash? Post 302399993 by Karthikeyan_113 on Tuesday 2nd of March 2010 04:22:33 AM

Barani,

i was thinking to declare the parameter that you want as output as OUT parameter and calling the function. But yeah... once you log into SQL, taking the parameter from SQL session to UNIX session is not possible.

OK... Leave that.

Lets try the other one.

Direct the output of the SQL session, to a file throught DBMS_OUTPUT.PUT_LINE statements.
and then read the variable from that file.

What do you think abt this one ?

EXECUTE(7)                                                         SQL Commands                                                         EXECUTE(7)

NAME
EXECUTE - execute a prepared statement SYNOPSIS
EXECUTE name [ ( parameter [, ...] ) ] DESCRIPTION
EXECUTE is used to execute a previously prepared statement. Since prepared statements only exist for the duration of a session, the pre- pared statement must have been created by a PREPARE statement executed earlier in the current session. If the PREPARE statement that created the statement specified some parameters, a compatible set of parameters must be passed to the EXECUTE statement, or else an error is raised. Note that (unlike functions) prepared statements are not overloaded based on the type or number of their parameters; the name of a prepared statement must be unique within a database session. For more information on the creation and usage of prepared statements, see PREPARE [prepare(7)]. PARAMETERS
name The name of the prepared statement to execute. parameter The actual value of a parameter to the prepared statement. This must be an expression yielding a value that is compatible with the data type of this parameter, as was determined when the prepared statement was created. OUTPUTS
The command tag returned by EXECUTE is that of the prepared statement, and not EXECUTE. EXAMPLES
Examples are given in the Examples [prepare(7)] section of the PREPARE [prepare(7)] documentation. COMPATIBILITY
The SQL standard includes an EXECUTE statement, but it is only for use in embedded SQL. This version of the EXECUTE statement also uses a somewhat different syntax. SEE ALSO
