Input Parameter

Description

QueryBandIn

Query band string.

SearchType

0 = Return the name-value pairs in both transaction and session query bands are returned. If the same name occurs in both the transaction and the session query bands, the value for the transaction query band is returned.

1 = Return only the name-value pairs in the transaction query band.

2 = Return only the name-value pairs in the session query band.

3 - Return only the name-value pairs in the profile query band.

 

Column Name

Description

QBName

Name of the query band.

QBValue

Value of the query band.

GetQueryBandPairs are two overloaded table functions. One requires the query band string to be passed in; the other uses internal calls to retrieve the query band.

Both functions are created in the SYSLIB database by the DEM DIP script. EXECUTE privileges are granted to PUBLIC by default. For more information, see “Requirements for Using the API” on page 19.

The following example shows how to call the GetQueryBandPairs function.

SELECT * FROM TABLE(GetQueryBandPairs(0)) AS t1;
 
 *** Query completed. 3 rows found. 2 columns returned.
 *** Total elapsed time was 1 second.
 
QBName    QBValue

The following example shows how to call the GetQueryBandPairs function using the MonitorQueryBand function as input.

SELECT * FROM TABLE(GetQueryBandPairs(MonitorQueryBand(1, 103, 16383), 0)) AS t1;
 
 *** Query completed. 3 rows found. 2 columns returned.
 *** Total elapsed time was 1 second.
