Question

Lets say i have a table like this:

    col1     col2     col3
row1  1       null    null

row2  null    2       null

row3  null    null    3

All data types are numbers, integers or long. And i need a table like this:

    col1     col2     col3
row1  1       2        3

How can i accomplish this with an sql statement? I assume i have to create a new table and insert a new row with a select statement, but i am more of a coder and not sure what kind of statement i should use. Thanks for the help.

sllev got me on the right track. In my case, because all values except for one were always going to be null in any given column, i just had to use the MAX() function. my final sql statement looked like this:

Select MAX(Merge_Table_Parcel_1.txtFrequency1) AS Frequency1,
       MAX(Merge_Table_Parcel_1.SUM_INST_N) AS SUM_INST_N1,
       MAX(Merge_Table_Parcel_1.SUM_INST_D) AS SUM_INST_D1,
       MAX(Merge_Table_Parcel_1.SUM_CTRN_D) AS SUM_CTRN_D1,
       MAX(Merge_Table_Parcel_1.SUM_CTRN_N) AS SUM_CTRN_N1,
       MAX(Merge_Table_Parcel_1.SUM_TRAN_N) AS SUM_TRAN_N1,
       MAX(Merge_Table_Parcel_1.SUM_PPU) AS SUM_PPU1,
       MAX(Merge_Table_Parcel_1.SUM_PPUJOBS) AS SUM_PPUJOBS1,
       MAX(Merge_Table_Parcel_1.SUM_DAYT) AS SUM_DAYT1,
       MAX(Merge_Table_Parcel_1.SUM_RESD_D) AS SUM_RESD_D1,
       MAX(Merge_Table_Parcel_1.SUM_RESD_N) AS SUM_RESD_N1,
       MAX(Merge_Table_Parcel_1.SUM_ON_STRN_D) AS SUM_ON_STRN_D1,
       MAX(Merge_Table_Parcel_1.SUM_ON_STRN_N) AS SUM_ON_STRN_N1
  FROM Merge_Table_Parcel_1

Simple, i know, but i dident see it right away. Thank you to everyone who contributed a response, and to sllev who pointed me in the right direction.
