conn.execute(『INSERT INTO parent VALUES (1, 'Parent 1'), (2, 'Parent 2')『) conn.execute(『INSERT INTO child VALUES (101, 1, 'Child 1'), (102, 2, 'Child 2')『) # 测试 1: 正常更新非键字段 try: logger.info(『测试 1: 更新 parent 表的非键字段『) conn.execute(『UPDATE par...
Using the previous output, you can query individual cells using standard Python indexing notation. The previous queries returned values from a specified cell or by using a specified value. The two queries that are to be followed will return values based on a point geometry. Using ST_NearestValu...
Integer division returning “incorrect” values division integerPython 2In Python 2.x integer division will result in an integer output, confusing users.>>> 1/2 0 >>> 1.0/2.0 0.5 Python 3In Python 3.x this issue is “fixed” by division of integers returning a float....
MEDIAN($F$6,$F$5,B5) determines the median between the cell values of F6, F5, and B5. IF(B5=MEDIAN($F$6,$F$5,B5),”On time”,”Late”) checks whether the value of B5 is equal to the median. If it is, the function returns “On time”. Otherwise, it returns “Late”. Pr...
