Shows the CREATE TABLE statement that was used to create the table.

Syntax

SHOW CREATE TABLE table_name

Arguments

table_name

The name of the table.

Remarks

• In the output, MemSQL specific table attributes are enclosed in the blocks /*! and */. These blocks are not comments, as the entire output of SHOW CREATE TABLE can be used to recreate the table.
• This command can be run on any MemSQL node (see Node Requirements for MemSQL Commands).

Examples

Example 1

The following example shows the output of SHOW CREATE TABLE for a table with sparse compression.

Create the table:

CREATE TABLE table_1(a INT, b DECIMAL) COMPRESSION = SPARSE;

Show the table:

SHOW CREATE TABLE table_1;

Output of the “Create Table” column for the table_1 row:

CREATE TABLE `table_1` (
  `a` int(11) DEFAULT NULL,
  `b` decimal(10,0) DEFAULT NULL
  /*!90618 , SHARD KEY () */
) /*!90623 AUTOSTATS_CARDINALITY_MODE=PERIODIC, AUTOSTATS_HISTOGRAM_MODE=CREATE */ /*!90623 SQL_MODE='STRICT_ALL_TABLES' */
  /*!90623 COMPRESSION=SPARSE */

Example 2

The following example shows the output of SHOW CREATE TABLE for a columnstore table.

Create the table:

CREATE TABLE table_2(a INT, b VARCHAR(50), KEY(b) USING CLUSTERED COLUMNSTORE);

Show the table:

SHOW CREATE TABLE table_2;

Output of the “Create Table” for the table_2 row:

CREATE TABLE `table_2` (
  `a` int(11) DEFAULT NULL,
  `b` varchar(50) CHARACTER SET utf8 COLLATE utf8_general_ci DEFAULT NULL,
  KEY `b` (`b`) /*!90619 USING CLUSTERED COLUMNSTORE */
  /*!90618 , SHARD KEY () */
) /*!90623 AUTOSTATS_CARDINALITY_MODE=INCREMENTAL, AUTOSTATS_HISTOGRAM_MODE=CREATE, AUTOSTATS_SAMPLING=ON */ /*!90623 SQL_MODE='STRICT_ALL_TABLES' */
