Support for the Teradata NUMBER data type has been added to SAS/ACCESS Interface to Teradata with SAS^® 9.4M7 (TS1M7) and SAS^® Viya^® 3.5. The Teradata NUMBER data type has a higher level of precision than SAS^® 9.4 supports so data truncation might occur.  

If you are not using the NUMBER data type in calculations but you want a higher level of precision than what SAS supports, you can use the Teradata CAST() function with explicit pass-through to change the column to the CHAR data type:

You can place the CAST() function in a Teradata view. You can also use the DBSASTYPE= data set option with the Teradata LIBNAME engine to convert it to the CHAR data type:  

Otherwise, the variable will be read in and stored as a different value from what existed in Teradata.

Trying to use an earlier version of SAS to read in a Teradata table that contains a NUMBER data type column might result in a note or error similar to one of the following:

• NOTE: The following 1 column(s) in TERALIB.test  have been automatically dropped because they have a datatype that is not supported by this engine:

• ERROR: At least one of the columns in this DBMS table has a datatype that is not supported by this engine.

To read in the NUMBER data type with an earlier version of SAS, you can use either the CAST or DBSASTYPE= approach discussed above to read it as a character. If the column has a level of precision that SAS supports, you can CAST it to a numeric data type that SAS supports or set the data type to NUMERIC with the DBSASTYPE= option:
