number of field from prop:sql

number of field from prop:sql

(OP)
Hi
how do I know how many fields will be output when using a Query "select * from ...." using {prop:sql}

thank you

RE: number of field from prop:sql

IF you use TABLE{PROP:SQL} = 'SELECT * FROM TABLE' you get all fields from TABLE.
WITH NEXT(TABLE) you sync the hole row.

RE: number of field from prop:sql

(OP)
My dear I know that I will get all fields from table with * . the question is I want to know how many.

RE: number of field from prop:sql

In Oracle for example, you can make a select in/before your other Main-Statement.

select count(*)
from ALL_TAB_COLUMNS
where TABLE_NAME = 'TABLE'

RE: number of field from prop:sql

(OP)
Also in SQL you will get the number of columns using:
SELECT count(*)
FROM INFORMATION_SCHEMA.COLUMNS
where TABLE_NAME = 'TableName'


but this is not the case, I gave an example as * to make it easier to explain but the query could be:

Select F1,F2 from Table

what I want to know is the number of output ( 2 in this case) although the Table could have 10 fields
