pandas.read_sql_table(table_name, con, schema=None, index_col=None, coerce_float=True, parse_dates=None, columns=None, chunksize=None)[source]

Read SQL database table into a DataFrame.

Given a table name and a SQLAlchemy connectable, returns a DataFrame. This function does not support DBAPI connections.

Parameters

table_name:str

Name of SQL table in database.

con:SQLAlchemy connectable or str

A database URI could be provided as str. SQLite DBAPI connection mode not supported.

schema:str, default None

Name of SQL schema in database to query (if database flavor supports this). Uses default schema if None (default).

index_col:str or list of str, optional, default: None

Column(s) to set as index(MultiIndex).

coerce_float:bool, default True

Attempts to convert values of non-string, non-numeric objects (like decimal.Decimal) to floating point. Can result in loss of Precision.

parse_dates:list or dict, default None

• List of column names to parse as dates.

• Dict of {column_name: format string} where format string is strftime compatible in case of parsing string times or is one of (D, s, ns, ms, us) in case of parsing integer timestamps.

• Dict of {column_name: arg dict}, where the arg dict corresponds to the keyword arguments of pandas.to_datetime() Especially useful with databases without native Datetime support, such as SQLite.

columns:list, default None

List of column names to select from SQL table.

chunksize:int, default None

If specified, returns an iterator where chunksize is the number of rows to include in each chunk.
