SQL Query for condition stored as column in table
SQL Query for condition stored as column in table
(OP)
Hi,
I need to form an SQL query to fetch the values from table A where conditions are satisfied. These conditions are stored in Table A itself in a column called "condition"
Could some one please help to form the query on this?
My table structure is as given
Table1: documentList
Field1: ID
Field2:Product_Name
Field3:condition
Field4:Document_Name
Table2: Department
field:ID
Field2: Dept_Name
Field3:Dept_Type
Field_type_Dept_code
the resultant value should fetch all the document_name where condition in condition column satisfies the result.
Note: Condition values are field name of Table 2 extactly same what we put in "WHERE" clause.
Sample Values in Table1 is
ID Product_Name Condition Document_name
1 Books Table2.Dept_code='101' Book1
2 Books Table2.Dept_code='102' Book2
3 laptop Table2.Dept_Type='IT' laptop1
I need a SQL query from above to get all records where condition in Table1 is such that Table2.Dept_code='101' satisfied
plz help

Also, conditon are unrestricted on field vales of table2, so I do not have control on it other than incorporating condition in table itself.
Do you have any other suggestion for above design.

RE: SQL Query for condition stored as column in table
e.g. give input data, input conditions ,e.g. how will your SQL be executed - how will you supply parameters (conditions) to it - how many conditions can there be?, what would be your desired output given the input data and input conditions, and everything else you can think of.
Please give examples of more than one number of parameters to the SQL and with enough input data samples to make it clear of what you are trying to accomplish

RE: SQL Query for condition stored as column in table
First you have to get your condition into the table. I assume you figured that out.
insert into table2 values (2,'docname = ' + char(39) + 'ASR08222184-1349-20090526' + char(39))
Then you have to set up your queries.
declare @test varchar(100)
declare @sqlstr varchar(300)
select @test = (select condition from table2 where id=2)
print @test
select @sqlstr = 'select * from document where ' + @test
print @sqlstr
exec (@sqlstr)
Good Luck.
