DB2 Merge SQL iSeries - php

Question

I created this function to update or insert a row based on if a row already exist, or not; the error I am getting is VAR1 is not a variable. This is my first time setting up a merge in this fashion on a iSeries and DB2. Hope someone can help, thanks to all that takes the time to do so.
function mergeRecord($var1, $var2, $var3, $var4, $var5, $var6){
db2RunSql("
MERGE INTO schema.tableName AR
USING (VALUES (:var1, :var2, var3, :var4, :var5, :var6)
FOR :var1 ROWS)
AS AC (VAR1, VAR2, VAR3, VAR4, VAR5, VAR6)
ON (AR.VAR1 = AC.VAR1 AND AR.VAR4 = AC.VAR4 AND AR.VAR6 = AC.VAR6)
WHEN MATCHED THEN UPDATE SET VAR1=?, VAR2=?, VAR3=?, VAR4=?, VAR5=?, VAR6=?
WHEN NOT MATCHED THEN INSERT (:var1, :var2, :var3, :var4, :var5, :var6)
VALUES (?, ?, ?, ?, ?, ?)",
array($var1, $var2, $var3, $var4, $var5, $var6)
);
}

Maybe you are looking for something like this:
function mergeRecord($var1, $var2, $var3, $var4, $var5, $var6){
db2RunSql("
MERGE INTO schema.tableName AR
USING (VALUES (?, ?, ?, ?, ?, ?))
AS AC (VAR1, VAR2, VAR3, VAR4, VAR5, VAR6)
ON (ar.var1, ar.var4, ar.var6) = (ac.var1, ac.var4, ac.var6)
WHEN MATCHED THEN
UPDATE SET (ar.var2, ar.var3, ar.var5) = (ac.var2, ac.var2, ac.var5)
WHEN NOT MATCHED THEN
INSERT VALUES (ac.var1, ac.var2, ac.var3, ac.var4, ac.var5, ac.var6)",
array($var1, $var2, $var3, $var4, $var5, $var6)
);
}
I think you are trying to insert too many parameter markers in your example when you could simply be using columns in the source (USING) table as update or insert values.
NOTE: This is just a guess as I am not sure what db2RunSql() does. It is not a standard function, and you have not provided a definition of it.
