Question

How can i convert following plsql to tsql. B.STATUS(+)=1 doesnt work in tsql.

  Select * from A,B where A.ID=B.ID(+)
     WHERE B.STATUS(+)=1

this doesnt return rows in mssql because it doesnt understand B.STATUS is optional

 Select * from A LEFT JOIN B ON A.ID=B.ID
WHERE B.STATUS=1

Answer 1

An OUTER JOIN changes to an INNER JOIN when a condition is applied to the outer table in the WHERE clause. In the ON clause, it stays as OUTER.

You need to push the predicate “in”

 Select * from A LEFT JOIN B ON A.ID = B.ID AND B.STATUS=1

OR

 Select * from
     A LEFT JOIN
     (SELECT * FROM B WHERE B.STATUS=1) B1 ON A.ID = B1.ID
