Ensure Primary Keys Are Enforced and MyISAM Engine Is Prohibited

OrtaDüzey 1Otomatiktdsql

Açıklama

TXSQL enforces "mandatory primary keys" and an "engine allowlist" through two kernel parameters plus Gateway-layer supplementation: sql_require_primary_key (MySQL 8.0 upstream) - a primary key is required when creating/altering tables reject_table_no_pk (TXSQL enhancement) - reject DML on tables without a primary key reject_create_table_myisam (TXSQL enhancement) - reject creation of MyISAM tables ... Runs the mysql client against the TDSQL data node selected by TDSQL_MYSQL_OPTS (e.g. "-h10.0.0.5 -P4001 -utdsql_audit"); keep the password in ~/.my.cnf or a login path rather than MYSQL_PWD or the command line (see 1.4 and 1.5). Passes when sql_require_primary_key, reject_table_no_pk and reject_create_table_myisam all exist and are ON; also run the benchmark query to find existing tables without a primary key or using MyISAM.

Nasıl denetlenir

Denetim yöntemi: SQL sorgusu

sql_query

out=$(mysql ${TDSQL_MYSQL_OPTS:-} -NBe "SHOW GLOBAL VARIABLES WHERE Variable_name IN ('sql_require_primary_key', 'reject_table_no_pk', 'reject_create_table_myisam')" 2>/dev/null) || exit 1; printf '%s\n' "$out" | awk -F'\t' 'NF >= 2 {n++; v = toupper($2); if (v == "ON" || v == "1") ok++} END {print (n == 3 && ok == 3) ? "compliant" : "noncompliant"}'

Beklenen çıktı: compliant

Nasıl düzeltilir

Düzeltme yöntemi: Kılavuz veya altyapı yaması

SET GLOBAL sql_require_primary_key = ON; SET GLOBAL reject_table_no_pk = ON; SET GLOBAL reject_create_table_myisam = ON; persist them in the parameter template and add primary keys / convert MyISAM tables to InnoDB.
