TRANSFORM Statement

Creates a crosstab query .

Syntax

TRANSFORM aggfunction
selectstatement
PIVOT pivotfield [IN (value1[, value2[, ...]])]

The TRANSFORM statement has these parts:

Part Description
aggfunction An SQL aggregate function that operates on the selected data.
selectstatement A SELECT statement.
pivotfield The field or expression you want to use to create column headings in the query's result set.
value1, value2 Fixed values used to create column headings.
Remarks

When you summarize data using a crosstab query, you select values from specified fields or expressions as column headings so you can view data in a more compact format than with a select query .

TRANSFORM is optional but when included is the first statement in an SQL string . It precedes a SELECT statement that specifies the fields used as row headings and a GROUP BY clause that specifies row grouping. Optionally, you can include other clauses, such as WHERE , that specify additional selection or sorting criteria. You can also use subqueries as predicates — specifically, those in the WHERE clause — in a crosstab query.

The values returned in pivotfield are used as column headings in the query's result set. For example, pivoting the sales figures on the month of the sale in a crosstab query would create 12 columns. You can restrict pivotfield to create headings from fixed values (value1, value2 ) listed in the optional IN clause. You can also include fixed values for which no data exists to create additional columns.
