6. 11.x core/lib/Drupal/Core/Database/Schema.php \Drupal\Core\Database\Schema::buildTableNameCondition()

Build a condition to match a table name against a standard information_schema.

The information_schema is a SQL standard that provides information about the database server and the databases, schemas, tables, columns and users within it. This makes information_schema a useful tool to use across the drupal database drivers and is used by a few different functions. The function below describes the conditions to be meet when querying information_schema.tables for drupal tables or information associated with drupal tables. Even though this is the standard method, not all databases follow standards and so this method should be overwritten by a database driver if the database provider uses alternate methods. Because information_schema.tables is used in a few different functions, a database driver will only need to override this function to make all the others work. For example see core/includes/databases/mysql/schema.inc.

Parameters

$table_name: The name of the table in question.

$operator: The operator to apply on the 'table' part of the condition.

$add_prefix: Boolean to indicate whether the table name needs to be prefixed.

Return value

\Drupal\Core\Database\Query\Condition A Condition object.
