##################################
#
# This include file will be used for all CREATE TABLE statements in the suite. 
# If you need to add additional steps or change the logic, copy the file 
# to storage/<engine>/mysql-test/storage_engine/ folder and modify it there.
#
##################
#
# Parameters: 
#
# --let $create_definition = <column names, types, indexes)   # optional, default a $int_col, b $char_col (based on defaults)
# --let $table_name = <table name>                            # optional, default t1
# --let $table_options = <table options>                      # optional, default based on define_engine.inc
# --let $partition_options = <partitioning definition>        # optional, default none
# --let $as_select = <SELECT statement>                       # optional, default empty
# --let $error_codes = <expected error codes, as in --error>  # optional, default 0
# --let $if_not_exists = [0|1]                                # optional, default 0 (1 adds IF NOT EXISTS clause)
# --let $default_engine = [0|1]                               # optional, default 0 (with 1 will rely on default engine, no ENGINE=)
# --let $temporary = [0|1]                                    # optional, default 0 (1 adds TEMPORARY)
# --let $disable_query_log = [0|1]                            # optional, default 0 (1 disables logging of CREATE)
#
# Usage examples:
#
# --source create_table.inc -- creates a default table
#
# --let $create_definition = a INT NOT NULL, b CHAR(1) PRIMARY KEY, INDEX(a)
# --let $table_options = AUTO_INCREMENT = 100
# --let $partition_options = PARTITION BY HASH(a) PARTITIONS 2
# --let $as_select = SELECT 1, 'a'
# --source create_table.inc
#
# Additionally, a test can define $extra_tbl_options. The difference with $table_options
# is that its value is persistent and will be used until it is unset explicitly, or
# until the test ends. The purpose of it is to allow one test to call another test,
# when the called test does not know about specific options the calling test might require,
# and thus cannot set them on per-create basis.
