Db2 select cast

Example 3: A CAST specification can be used to explicitly specify the data type of a parameter in a context where a parameter marker must be typed. You can use cast functions or CAST specification to explicitly cast a data type to another data type. DbCAST expression overview. For example, if you have a column of dates (BIRTHDATE) defined as DATE and want to cast the column data type to CHARACTER with a fixed length of 1 enter the following: SELECT CHAR (BIRTHDATE,USA) FROM CORPDATA. For a cast operand that is an expression, the supported target data types depend on the data type of the cast operand (source data type).

The length attribute and the CCSID attribute of the result of the cast are determined in the same way as the VARCHAR function. However, in CAST specification, when an unqualified distinct type is specified as the target data type, DBfirst resolves the schema name of the distinct type and then uses that schema name to locate the cast function. Function resolution is similar for both.

In general, the value of the case-expression is the value of the result-expression following the first (leftmost) when-clause that evaluates to true. If no case evaluates to true and the ELSE keyword is present, the result is the value of the result-expression or NULL. How to convert data types on DB2.
