使用黑色格式化程序在 Python 中的多行 SQL 语句格式化

Question

When formatting, black ends up concatenating multiline SQL statements:

Before formatting:

df = pd.read_sql(
"SELECT TOP 1000 * " \
"FROM [ETZ3BSC1].[NT0001\BD9524].[AA_Trades]", conn
)

After formatting:

df = pd.read_sql(
    "SELECT TOP 1000 * " "FROM [ETZ3BSC1].[NT0001\BD9524].[AA_Trades]", conn
)

Is it possible to enable multi-line SQL statement support? Adding # fmt: off and # fmt: on before and after the code works but I'm interested in multi-line SQL code support, not disabling the formatter completely.

Answer 1

Python's multiline string syntax should work here:

df = pd.read_sql("""
    SELECT TOP 1000 *
    FROM [ETZ3BSC1].[NT0001\BD9524].[AA_Trades]""", conn
)
