Oracle mode makes the following changes to NULL handling: NULL As a Statement
The following syntax has been supported since MariaDB 10.3.5: If one does a SHOW CREATE TABLE in ORACLE mode on a table that has a native MariaDB DATE column, it will be displayed as mariadb_schema.date to not conflict with the Oracle DATE type. This was implemented as part of MDEV-10343. Oracle mode makes the following changes to Prepared Statements: These functions can also be accessed outside of ORACLE mode by suffixing _ORACLE onto the end of the function name, such as TRIM_ORACLE. Returns NULL instead of an empty string if returning an empty result. All modes.Īdded to enhance Oracle compatibility. Position 0 for substr() is same as position 1 Returns a VARCHAR(1) with character set and collation according to and ,3) same as substr('abc', 1 ,3) In all modes one can use LENGTHB() as a synonym to OCTET_LENGTH() MariaDB translates LENGTH() to OCTET_LENGTH(). In Oracle mode, compares and matches search expressions All modes.Ĭast expression to a VARCHAR(N). MDEV-10578Īdded as a wrapper for DATE_ADD() to enhance Oracle compatibility. Returns the error message associdated to it's error number argument or SQLCODE if no argument is given.
WHILE LOOP IN ORACLE 10G CODE
Returns the number code of the most recent exception. In MariaDB mode, variables must be declared before cursors. Variables can be declared after cursor declarations MDEV-12133ĬURSOR c1 IS SELECT a,b FROM t1 rec1 c1%ROWTYPE
Var:= 10 Can also be used with MariaDB systemvariables Oracle mode makes the following changes to Cursors: MariaDB mode only supports RETURNS in stored functions Can also be used in stored proceduresĪNSI uses RETURNS. In Oracle mode one can call other stored procedures with name only. MDEV-10596Ĭreates an aggregate function, which performs the function against a set of rows and returns one aggregate result. The length is inherited from the argument at call time. VARCHAR can be used without length for routine parameters and RETURN clause. If function has no parameters then parentheses must be omittedĮxample: CREATE PROCEDURE p1 AS BEGIN NULL END CREATE FUNCTION f1 RETURN NUMBER AS BEGIN.ĬREATE FUNCTION f1 RETURN NUMBER IS BEGIN.
