Uses an operator to combine several queries into one query. For example, you can generate queries as "C1 AND C2 AND C3", "(C1 AND C2) OR C3", or "(C1 AND C2) OR (C3 AND C4).

Note  The Merge Queries VI creates a new query reference. The input query references are not closed automatically. Use the Close Reference VI to close query references.

Merge Queries

/images/reference/en-XX/help/372745E-01/crn.gif query reference in 1 is the first query that is to be connected to other queries.
/images/reference/en-XX/help/372745E-01/crn.gif query reference in 2 is the second query that is to be connected to other queries.
/images/reference/en-XX/help/372745E-01/c1drn.gif query reference array in is an array of queries that are to be connected to each other or to other queries.
/images/reference/en-XX/help/372745E-01/cenum.gif operation specifies which operator (AND or OR) is used to connect the queries. The default DataFinder operator is AND.
/images/reference/en-XX/help/372745E-01/ccclst.gif error in (no error) describes error conditions that occur before this node runs. This input provides standard error in functionality.
