Question
Which of the following statements is wrong?Question 30Select one:a.SQL INSERT command is used to add data to a tableb.A data type of Char(30) indicates a fixed-length field of 30 charactersc.SQL was developed by IBM in the late 1970sd.While creating a table using SQL, specifying the NULL property for a column means that only null values can be stored in that column
Solution
The incorrect statement is:
d. While creating a table using SQL, specifying the NULL property for a column means that only null values can be stored in that column
This is incorrect because in SQL, specifying the NULL property for a column means that the column can accept null values, not that it can only store null values. It can also store other data types like integers, strings, etc. depending on the data type of the column.
