SAS/ACCESS Interface to Oracle 4 ACCESS Procedure Data Conversions 737ACCESS Procedure Data ConversionsThe following table shows the default SAS variable formats that SAS/ACCESSassigns to Oracle data types when you use the ACCESS procedure .Table 25.6PROC ACCESS: Default SAS Formats for Oracle Data TypesOracle Data TypeDefault SAS FormatCHAR(n) $n.

If Oracle data falls outside valid SAS data ranges, the values areusually counted as missing.The following table shows the correlation between the Oracle NUMBER data typesand the default SAS formats that are created from that data type.Table 25.7Default SAS Formats for Oracle NUMBER Data TypesOracle NUMBER Data Type Rules Default SAS FormatNUMBER(p) 0 < p 0,s 0,s >0,s < p (p + 2).sNUMBER(p,s) p >0,s >0,s >= p (s + 3).sNUMBER(p) p > 32 BEST22. SAS selects formatNUMBER p, s unspecified BEST22. SAS selects formatThe general form of an Oracle number is NUMBER(p,s) where p is the precision ands is the scale of the number. Oracle defines precision as the total number of digits, witha valid range of -84 to 127. However, a negative scale means that the number isrounded to the specified number of places to the left of the decimal. For example, if thenumber 1,234.56 is specified as data type NUMBER(8,-2), it is rounded to the nearesthundred and stored as 1,200.
