Generates a dialect-aware COUNT(*) wrapper around a subquery.
This utility is used to compute the total number of rows returned by an arbitrary SQL query by wrapping it in:
SELECT COUNT(*) AS count FROM (
The alias token is generated through getAliasToken, so dialects
that do not support the AS keyword (e.g. Oracle) are handled correctly.
The SQL query to wrap inside the COUNT(*) subquery.
const subQuery = `SELECT * FROM "Users" WHERE "active" = true`;
const countQuery = queryGenerator.generateCountAllQuery(subQuery);
// SELECT COUNT(*) AS count FROM (SELECT * FROM "Users" WHERE "active" = true) AS Z
// (Oracle)
// SELECT COUNT(*) AS count FROM (SELECT * FROM "Users" WHERE "active" = true) Z
Generates a unique identifier for the current transaction.
Generates an SQL query that returns all foreign keys of a table or the foreign key constraint of a given column.
The table or associated model.
Optional_columnName: stringThe name of the column. Not supported by SQLite.
The generated SQL query.
Use showConstraintsQuery instead.
⚠️ This is not an identifier, it's a raw SQL expression. It will be inlined in the query.

Whether the result should be unquoted (depending on dialect: ->> and #>> operators, json_unquote function). Defaults to false.

This is a temporary class used to progressively migrate the AbstractQueryGenerator class to TypeScript by slowly moving its functions here. Always use AbstractQueryGenerator instead.
