Mysql insert into where is null

Duplicates indicates the number of rows that could not be inserted because they would duplicate some existing unique index value. Warnings indicates the number of attempts to insert column values that were problematic in some way. Warnings can occur under any of the following conditions:. Instead, the statement fails with an error. Setting a numeric column to a value that lies outside the column range. The value is clipped to the closest endpoint of the range.

Assigning a value such as ' The trailing nonnumeric text is stripped off and the remaining numeric part is inserted. If the string value has no leading numeric part, the column is set to 0. The value is truncated to the column maximum length. Inserting a value into a date or time column that is illegal for the data type. The column is set to the appropriate zero value for the type. These two functions do not always behave identically. See Section 8. It also causes concurrent inserts not to be used.

Ignored errors generate warnings instead. IGNORE has a similar effect on inserts into partitioned tables where no partition matching a given value is found. For an example, see Section With IGNORE , invalid values are adjusted to the closest values and inserted; warnings are produced but the statement does not abort.

Thanks, i'll have to add some additional testing and explicitly set the nulls, it is much more logical in the application that the fields are null rather than empty strings. Unfortunately, quoting the field will be incorrect, if the value to be inserted is NULL. Micah Fagre Micah Fagre 51 1 1 silver badge 2 2 bronze badges. Sign up or log in Sign up using Google.
