How to change the matrix int variable to just int variable?

i am working with databases like postgresql, the problem is i try to send a variable of just int, but for the program it is a matrix that can't be resolved, is there a way to remove that matrix and have it as just a normal variable in matlab with integer type?

Ziad - please describe how you are sending the data from MATLAB to the database? Are you constructing some sort of SQL command to update a table with a new value?

All variables in matlab are matrices. There is no such thing as a non-matrix variable. Even scalar cell arrays, structures, objects, etc. are matrices of size 1x1.

Note: see this description of the XY problem and please tell use which is the real problem you're trying to solve.
