How to append data

SKP — Mon, 23 Jan 2017 21:19:09 GMT

Hi,

I'm trying to append data from one table to the other and create new table with UNION ALL query, but got the error which seems to be due to NULL value in one of the field.

Can someone please let me know how I should do this?

Here is what I am trying to do:

In table 1, I have

Customer ID

Cutomer Name

Location

Product ID

Purchase amount in Jan

Purchase amount in Feb

Purchase amount in March

Purchase amount in April

In table 2, I have

Cutomer Name

Product ID

Purchase amount in Jan

Purchase amount in Feb

Purchase amount in March

Purchase amount in April

I'm trying to append data in table 2 to table 1, and rename it as C.

Thank you for your help.

Have you tried PROC APPEND or a data step?

data want;

set table1 table2;

run;

I've tried PROC SQL.

Hi Kurt,

I have query as:

Proc Sql;

Create table C as

Select * from table 1

Union

Select * from table 2;

quit;

Error log says:

Colum 1 from the first contributer of UNION is not the same type as its counterpart from the second

Thanks,

SAS requires variables to be of the same type when combining data in a column. So whatever is in the first column of TABLE 1 is not the same type as Table2. Either both character or both numeric.

And your syntax won't run as you have spaces between table and the 1 or 2.

Proc contents on your data sets will tell you what variables are in each position and their data type.

It helps when you have a error to COPY the code and any messages from the log and PASTE into a code box opened with the {i} forum icon. Error messages are sometimes position sensitive and the forum windows will alter the formatting from as displayed in the log window.
