| Hi,I have a select query, but facing problems because of null values.Select t1.*,t2.project_name from Sales_DB..item_master t1,Project_DB..project_master..t2 where t1.invoice_no='100' and t2.project_code=t1.project_codeFrom the above query, table t1.project_code is null values [no datas are there] and table t2.project_code is also contains null values [no data].So how to select for this type of value...Thanks For The Guidences..Paramu @ PARANTHAMAN |

project_code is used to join item_master with project_master hence it makes no sense to join the null values and it makes no sense that project_code is null.Maybe you can be more clear with example data and wanted output.
No, you're never too old to Yak'n'Roll if you're too young to die. |

do you mean this?Select t1.*,t2.project_name from Sales_DB..item_master t1join Project_DB..project_master t2 on isnull(t2.project_code,-1)=isnull(t1.project_code,-1)where t1.invoice_no='100' |

Sorry but I can see no sense on joing unrelated records.
