数组 – 在PL / pgSQL中创建一个带有动态查询的数组

ERROR:  syntax error at or near "EXECUTE"

                                                         ^

有人可以帮帮我吗？
这是函数本身：

CREATE OR REPLACE FUNCTION deleteMAPPINGs(
   mapTable1_key text,mapping_table text,mapTable2_key text,table2 text,table2_key text,inputIdsToDelete bigint[]) RETURNS bigint[] AS
$BODY$
DECLARE
    outputIdsToDelete bigint[];
    findAllQuery text;
    findUnreferencedQuery text;
    BEGIN
    findAllQuery := 'SELECT DISTINCT ' || mapTable2_key ||
        ' FROM '  || mapping_table ||
        ' WHERE ' || mapTable1_key || ' = ANY(inputIdsToDelete)';
    findUnreferencedQuery := 'SELECT DISTINCT ' || table2_key || --find unused
        ' FROM ' || table2 ||
        ' WHERE ' || table2_key || ' NOT IN (' ||
            'SELECT DISTINCT ' || mapTable2_key || --all used
            ' FROM ' || mapping_table || ')';

    SELECT DISTINCT INTO outputIdsToDelete ARRAY( EXECUTE findAllQuery );

    DELETE FROM mapping_table WHERE 
        mapTable1_key = ANY(inputIdsToDelete) AND
        mapTable2_key = ANY(outputIdsToDelete);

    SELECT DISTINCT INTO outputIdsToDelete --overwrite with unused
        ARRAY(EXECUTE findUnreferencedQuery);

    RETURN outputIdsToDelete;
END;
