(create-migration-table! db modify-sql-fn table-name)
Creates the schema for the migration table via t-con in db in table-name
Creates the schema for the migration table via t-con in db in table-name
(migrate-up* db
{:keys [tx-handles-ddl?] :as config}
{:keys [name] :as migration})
(table-exists? db table-name)
Checks whether the migrations table exists, by attempting to select from
it. Note that this appears to be the only truly portable way to determine
whether the table exists in a schema which the db
configuration will find
via a SELECT FROM
or INSERT INTO
the table. (In particular, note that
attempting to find the table in the database meta-data as exposed by the JDBC
driver does not tell you whether the table is on the current schema search
path.)
