Question

当我从pyodbc连接中写出时，正在寻求有关特定错误的帮助。我该如何解决错误：

尚不支持ODBC SQL类型-360。 column-index = 1 type = -360'，来自PYODBC的“ HY106”错误

这是我的代码：

import pyodbc
import pandas as pd
import sqlparse

## Function created to read SQL Query
def create_query_string(sql_full_path):
    with open(sql_full_path, 'r') as f_in:
        lines = f_in.read()

    # remove any common leading whitespace from every line
    query_string = textwrap.dedent("""{}""".format(lines))
    ## remove comments from SQL Code
    query_string = sqlparse.format(query_string, strip_comments=True)

    return query_string

query_string = create_query_string("Bad Code from R.sql")

## initializes the connection string
curs = conn.cursor()

df=pd.read_sql(query_string,conn)

df.to_csv("TestSql.csv",index=None)

我们在查询字符串中使用以下SQL代码：

SELECT loss_yr_qtr_cd, 
       CASE 
         WHEN loss_qtr_cd <= 2 THEN loss_yr_num 
         ELSE loss_yr_num + 1 
       END                    AS LOSS_YR_ENDING, 
       snap_yr_qtr_cd, 
       CASE 
         WHEN snap_qtr_cd <= 2 THEN snap_yr_num 
         ELSE snap_yr_num + 1 
       END                    AS CAL_YR_ENDING,

只是看看如何正确地写出数据库。
