Database Reference
In-Depth Information
To specify a character set and collation for a table,
CREATE TABLE
(seen
in Chapter 21, “Creating and Manipulating Tables”) is used with additional
clauses:
▼
Input
CREATE TABLE mytable
(
columnn1 INT,
columnn2 VARCHAR(10)
) DEFAULT CHARACTER SET hebrew
COLLATE hebrew_general_ci;
▼
Analysis
This statement creates a two column table, and specifies both a character set
and a collate sequence.
In this example both
CHARACTER SET
and
COLLATE
were specified, but if
only one (or neither) is specified, this is how MariaDB determines what to use:
■
If both
CHARACTER SET
and
COLLATE
are specified, those values are
used.
■
If only
CHARACTER SET
is specified, it is used along with the default
collation for that character set (as specified in the
SHOW CHARACTER
SET
results).
■
If neither
CHARACTER SET
nor
COLLATE
is specified, the database
default is used.
In addition to being able to specify character set and collation tablewide,
MariaDB also allows these to be set per column, as seen here:
▼
Input
CREATE TABLE mytable
(
columnn1 INT,
columnn2 VARCHAR(10),
column3 VARCHAR(10) CHARACTER SET latin1 COLLATE latin1_general_ci
) DEFAULT CHARACTER SET hebrew
COLLATE hebrew_general_ci;
▼
Analysis
Here
CHARACTER SET
and
COLLATE
are specified for the entire table as well
as for a specific column.
