The form that I am working on has a key block Swamajr_Key_Block followed by the first database block, Swbmajr further down the list. When I enter all the values into the text items in the key block and press Page Down, then control will move to the Swbmajr block. The Swbmajr block is tied to the table Swbmajr. In the WHERE clause property of this data block, I wish to write the following code:
SELECT A.SWBMAJR_SBGI_CODE, A.SWBMAJR_MAJR_CODE, A.SWBMAJR_CONC_CODE,
A.SWBMAJR_DEGT_TRNS, A.SWBMAJR_DEGC_INST, A.SWBMAJR_YEAR_CODE
FROM SWBMAJR A
WHERE A.SWBMAJR_SBGI_CODE = :Swamajr_Key_Block.Inst_Co
AND Swbmajr_degt_trns = :Swamajr_Key_Block.Degt_Tr
AND Swbmajr_degc_inst = :Swamajr_key_block.degc_in
AND Swbmajr_majr_code = :Swamajr_key_block.majr_co
AND Swbmajr_conc_code = :Swamajr_key_block.conc_co
AND Swbmajr_acyr_code =
(SELECT MAX (B.swbmajr_acyr_code)
FROM swbmajr B
WHERE B.SWBMAJR_ACYR_CODE <= :Swamajr_key_block.term_co
AND B.SWBMAJR_SBGI_CODE = A.SWBMAJR_SBGI_CODE
AND B.SWBMAJR_DEGT_TRNS = A.SWBMAJR_DEGT_TRNS
AND B.SWBMAJR_DEGC_INST = A.SWBMAJR_DEGC_INST
AND B.SWBMAJR_MAJR_CODE = A.SWBMAJR_MAJR_CODE
AND B.SWBMAJR_CONC_CODE = A.SWBMAJR_CONC_CODE);
My question is how can I put the alias A in the FROM statement when the properties for the data block starts with the WHERE Clause? What I mean is that there is no FROM clause for me to put SWBMAJR A. Or could I just use the keyblock values in there too, i.e. AND B.SWBMAJR_SBGI_CODE = :Swamajr_Key_Block.Inst_Co
AND B.SWBMAJR_DEGT_TRNS = :Swamajr_Key_Block.Inst_Co

The query is correct, but what I am trying to say is that within the data block itself, there is no place to put the first part of the query, i.e.
SELECT A.SWBMAJR_SBGI_CODE, A.SWBMAJR_MAJR_CODE, A.SWBMAJR_CONC_CODE,
A.SWBMAJR_DEGT_TRNS, A.SWBMAJR_DEGC_INST, A.SWBMAJR_YEAR_CODE
FROM SWBMAJR A
because you can only start typing from the WHERE onwards.
It's hard for me to explain, so I have attached a snapshot.

Geeta, I believe I follow your problem, and this is only an educated guess -- unless your tool allows for SQL injection, or altering the code prior to the WHERE clause, that's not going to work. And if you are not acquinted with SQL injection, please search the EE knowledge base or Oracle to read why that's a serious no-no.
Geeta,
It is possible to write your own query but I can't reach my example know (I' am at home) .
Try to change the "query data source type' -property to "from clause query" and enter your query in the query datasource name. Maybe you wil have to fill the datasource columns.
Tomorrow I will check at work
found it
"query data source type" > "from clause query")
"query data source name " > select .... from ....
"query data source colums" > more fill in the columns you want to use : matching the database colums in your block
I don't know if its possible to use the :Swamajr_Key_Block.Degt_Tr
May be you will have to put these argument in the standard where clause.
Using the argument :Swamajr_key_block.term_co
Good luck!
You can always consider to get the arguments on the server side by setting then as context variables
before executing the query : in that case you can use them in de select query directly
I did some testing
you can't refer to an alias in an "from clause query" because oracle forms treats it as an inline query (see attached file aliashidden.jpg)
and
you can't refer to a bindvariable in an "from clause query" (see attached file no-bindvariable-allowed.jp
So you can define your own query in forms but It wil not solve your problem.
Looking in more detail at your query I think you can rewrite it so it doesn't needs the A.
-- this in your regular table/item-definition
SELECT A.SWBMAJR_SBGI_CODE, A.SWBMAJR_MAJR_CODE, A.SWBMAJR_CONC_CODE,
A.SWBMAJR_DEGT_TRNS, A.SWBMAJR_DEGC_INST, A.SWBMAJR_YEAR_CODE
FROM SWBMAJR
-- this in the where clause
WHERE SWBMAJR_SBGI_CODE = :Swamajr_Key_Block.Inst_Co
AND Swbmajr_degt_trns = :Swamajr_Key_Block.Degt_Tr
AND Swbmajr_degc_inst = :Swamajr_key_block.degc_in
AND Swbmajr_majr_code = :Swamajr_key_block.majr_co
AND Swbmajr_conc_code = :Swamajr_key_block.conc_co
AND Swbmajr_acyr_code =
(SELECT MAX (B.swbmajr_acyr_code)
FROM swbmajr B
WHERE B.SWBMAJR_ACYR_CODE <= :Swamajr_key_block.term_co
AND B.SWBMAJR_SBGI_CODE = :Swamajr_Key_Block.Inst_Co
AND B.SWBMAJR_DEGT_TRNS = :Swamajr_Key_Block.Degt_Tr
AND B.SWBMAJR_DEGC_INST = :Swamajr_key_block.degc_in
AND B.SWBMAJR_MAJR_CODE = :Swamajr_key_block.majr_co
AND B.SWBMAJR_CONC_CODE = :Swamajr_key_block.conc_co
errormessage using the alias form the from clause query in the where clause
errormessage using a bindvariable in the from clause query
from clause query example with bindvariable that will not work
Maybe you can try this tip:
create master-detail relation between blocks Swamajr_Key_Block and Swbmajr
( relation SWBMAJR_SBGI_CODE = :Swamajr_Key_Block.Inst_Co
AND Swbmajr_degt_trns = :Swamajr_Key_Block.Degt_Tr
AND Swbmajr_degc_inst = :Swamajr_key_block.degc_in
AND Swbmajr_majr_code = :Swamajr_key_block.majr_co
AND Swbmajr_conc_code = :Swamajr_key_block.conc_co
and set default_where property of Swbmajr (detail) block to
Swbmajr_acyr_code =
(SELECT MAX (B.swbmajr_acyr_code)
FROM swbmajr B
WHERE B.SWBMAJR_ACYR_CODE <= :Swamajr_key_block.term_co
AND B.SWBMAJR_SBGI_CODE = :Swamajr_Key_Block.Inst_Co
AND B.SWBMAJR_DEGT_TRNS = :Swamajr_Key_Block.Degt_Tr
AND B.SWBMAJR_DEGC_INST = :Swamajr_key_block.degc_in
AND B.SWBMAJR_MAJR_CODE = :Swamajr_key_block.majr_co
AND B.SWBMAJR_CONC_CODE = :Swamajr_key_block.conc_co
