Function Documentation

push_deprecated_warn()

void push_deprecated_warn ( THD *  thd, const char *  old_syntax, const char *  new_syntax  )

inline

Generates a warning that a feature is deprecated.

Using it as push_deprecated_warn(thd, "BAD", "'GOOD'"); Will result in a warning: "The syntax 'BAD' is deprecated and will be removed in a future release. Please use 'GOOD' instead"

If a function is deprecated, it should implement Item_func::is_deprecated() to return true to prevent the usage of the function in the generated column expression.

Parameters

thd	Thread context. If NULL, warning is written to the error log, otherwise the warning is sent to the client.
old_syntax	Deprecated syntax.
new_syntax	Replacement syntax.

push_deprecated_warn_no_replacement()

void push_deprecated_warn_no_replacement ( THD *  thd, const char *  old_syntax  )

inline

Generates a warning that a feature is deprecated.

Using it as push_deprecated_warn_no_replacement(thd, "old"); Will result in a warning: "The syntax 'old' is deprecated and will be removed in a future release.

If a function is deprecated, it should implement Item_func::is_deprecated() to return true to prevent the usage of the function in the generated column expression.

Parameters
