How it works. First, we convert the MySQL String Length string into ucs2 character set, which is UCS-2 Unicode that holds 2-byte characters.; Second, we use the CHAR_LENGTH and LENGTH functions to get the length of the @s string in bytes and in characters. Because the @s string contains 2-byte characters, its length in character is 19, while its length in bytes is 38 Briefly, however, a package is a container for multiple functions and procedures. Oracle extends PL/SQL with many supplied or built-in packages. This next example block declares a variable of type VARCHAR2 (string) with a maximum length of 100 bytes to hold the string 'Hello World!'. DBMS_OUTPUT.PUT_LINE then accepts the variable, rather. The above code now returns groups of strings for each department where the total length of each group is less than 25 characters: SELECT deptno, LISTAGG(ename, ';') WITHIN GROUP (ORDER BY empno) AS namelist, LENGTH(LISTAGG(ename, ';') WITHIN GROUP (ORDER BY empno)) AS how_long FROM emp_mr GROUP BY deptno, mno The %T specifier is always a valid SQL literal of a similar type, such as a wider numeric type. The literal will not include casts or a type name, except for the special case of non-finite floating point values. The STRING is formatted as follows: Type %t %T: NULL of any type: NULL: NULL: INT64: 123: 123: NUMERIC: 123.0 (always with .0) NUMERIC 123.0 FLOAT64: 123.0 (always with .0) 123e+10.
