LOOKUP FUNCTION

[#1]

Please help me with lookup function.

TEST1:

LOAD * INLINE [

KEY, VALUE

KEY1, 1

KEY2, 2

KEY3, 3

];

TEST2:

LOAD * INLINE [

KEY, VAL

KEY1, A

KEY2, B

KEY3, C

];

I need test 3 table to populate as

KEY,Val,Value (which comes from test1 table)

TEST3:

LOAD *,LOOKUP(VALUE,KEY,KEY,'TEST1') AS TEST

RESIDENT TEST2;

DROP TABLE TEST1;

DROP TABLE TEST2;

Use the mapping load and applymap function as done below. Note that mapping load tables don't need to be dropped.

Edit: And if you want to use your lookup function just add single quotes to the first 2 parameters: LOOKUP('VALUE','KEY',KEY,'TEST1')

TEST1:

MAPPING
LOAD * INLINE [

KEY, VALUE

KEY1, 1

KEY2, 2

KEY3, 3

];

TEST2:

LOAD * INLINE [

KEY, VAL

KEY1, A

KEY2, B

KEY3, C

];

I need test 3 table to populate as

KEY,Val,Value (which comes from test1 table)

TEST3:

LOAD *,applymap('TEST1',KEY) AS TEST

RESIDENT TEST2;

//DROP TABLE TEST1;

DROP TABLE TEST2;
