Insert file content (with white line and special characters ) in bash variable for insert in oracle table with sqlplus

I write this simpe test.ksh scipt:

#!/bin/ksh

TEST=$(cat $1 )
sqlplus -S *****/*****@*****<<- EOF

set define off;
SET SQLBLANKLINES ON;
INSERT INTO DBADOC.TEST
(
        "TEST"
)
 VALUES
(
      q'[ $TEST ]'
)
;
commit;
EOF

exit

************************************************ Now if i run it with a simple file (3 lines without special char): ./test.ksh /home/oracle/scripts/test.txt 1 row created. Commit complete. **It runs perfectly.** If I choose a complex file (with blank lines and special character ), it doesn't work: ./test.ksh /home/oracle/scripts/check_free_space_dg.ksh SP2-0734: unknown command beginning "# ========..." - rest of line ignored. SP2-0734: unknown command beginning "# @(#) NOM..." - rest of line ignored. SP2-0734: unknown command beginning "# @(#) GRU..." - rest of line ignored. SP2-0734: unknown command beginning "# @(#) DES..." - rest of line ignored. SP2-0044: For a list of known commands enter HELP and to leave enter EXIT. [...]
