Using associative arrays with an if statement

I have this piece of code. The first if statement is not working, however the second if statement is working fine.

I have set a value for Srcs to be file.srcs and want to print it.
If no value for Rcvs is set, I get the print statement correctly

Code:
hasValue[Srcs]="file.srcs"
if ${hasValue[Srcs]}; then
  echo "Value[Srcs] = ${hasValue[Srcs]}"
fi

if ! ${hasValue[Rcvs]}; then
  echo "No value for Rcvs"
fi

db2_stmt_error - Returns a string containing the SQLSTATE returned by an SQL statement

SYNOPSIS
string db2_stmt_error ([resource $stmt]) DESCRIPTION
Returns a string containing the SQLSTATE value returned by an SQL statement. If you do not pass a statement resource as an argument to db2_stmt_error(3), the driver returns the SQLSTATE value associated with the last attempt to return a statement resource, for example, from db2_prepare(3) or db2_exec(3). To learn what the SQLSTATE value means, you can issue the following command at a DB2 Command Line Processor prompt: db2 '? $sqlstate- value'. You can also call db2_stmt_errormsg(3) to retrieve an explicit error message and the associated SQLCODE value. PARAMETERS
o $stmt - A valid statement resource. RETURN VALUES
Returns a string containing an SQLSTATE value. SEE ALSO
db2_conn_error(3), db2_conn_errormsg(3), db2_stmt_errormsg(3). PHP Documentation Group DB2_STMT_ERROR(3)
