i need a query to result like

MainId     Col1    col2     price   name    date

2           qq      qq      price   name    date

This requires 3 different columns to be made on 3 different conditions for a MainID ; forming a single row.

You should be able to do the following by joining on multiple embedded queries:

Select 
      table1.MainID, table1.col1, table1.col2, q1.price, q2.name, q3.date
from 
table1 
left outer join (select 
                 MainID, lineNo, Text as price 
                 from 
                 table2) q1 on table1.MainID = q1.MainID
left outer join (select 
                 MainID, lineNo, Text as name 
                 from table2) q2 on table1.MainID = q2.MainID
left outer join (select 
                 MainID, lineNo, Text as date 
                 from table2) q3 on table1.MainID = q3.MainID
