Get rows from table. Columns and conditions can be set to filter result.
Arguments
| Argument | Type | Default value |
|---|---|---|
| table | null | |
| columns | str, None | None |
| conditions | str, None | None |
| as_table | bool, None | True |
| param table: | name of the SQL table |
|---|---|
| param columns: | name of columns to return, defaults to None means that all columns are returned |
| param conditions: | limiting result by WHERE clause, defaults to None |
| param as_table: | if result should be instance of Table, defaults to True False means that return type would be list |
| returns: | table or list based on param as_table arguement |

Execute a SQL query and optionally return the execution result.
Arguments
| Argument | Type | Default value |
|---|---|---|
| statement | str | null |
| assertion | str, None | None |
| sanstran | bool, None | False |
| as_table | bool, None | True |
| returning | bool, None | None |
| data | Dict, Tuple, None | None |
Security Warning: In order to safely include untrusted data in SQL queries it is advisable to use parameterized queries. For more information about formatting for specific databases, please see https://bobby-tables.com/python
| param statement: | SQL statement to execute. |
|---|---|
| param assertion: | Assert on query result, row_count or columns. Works only for SELECT statements. (defaults to None) |
| param sanstran: | Run the query without an implicit transaction commit or rollback if such additional action was detected and this is set to True. (turned off by default, meaning that commit is performed on successful queries and rollback on failing ones automatically) |
| param as_table: | If the result should be an instance of Table, otherwise a list will be returned. (defaults to True) |
| param returning: | Set this to True if you want to have rows explicitly returned (instead of the query result), False otherwise. (by default a heuristic detects if it should return or not) |
| param data: | The data to use if the SQL statement is parameterized |
| returns: | Fetched rows when returning is True or if the heuristic decides that the statement should return (raw rows or as Table if as_table is True), otherwise the object produced by the execution is returned. |
