Tweak your message to as needed to get the parameter lengths and
quotes correct.

ADDMSGD MSGID(TMP0001)
MSGF(mylib/mymsgf)
MSG('SQL STRING for my CL program.')
SECLVL('UPDATE TESTFILE
SET LG_ERRMSG=''&1'' LG_ERPATH=''&2''
WHERE LG_DATE=&3 AND LG_TIME=&4 AND LG_ID=''&5''
AND LG_SEQ=''&6'' AND LG_CLIENT=''&7''')
FMT((*CHAR 7) (*CHAR 10) (*CHAR 10) (*CHAR 10)
(*CHAR 10) (*CHAR 10) (*CHAR 10))

<<SNIP>>

If using that technique, surely the use of *QTDCHAR data type for the message data fields representing quoted character string literals would be better, to also avoid the escaped apostrophes in the ADDMSGD?

ADDMSGD
...
SECLVL('UPDATE TESTFILE
SET LG_ERRMSG=&1, LG_ERPATH=&2 ...
FMT((*QTDCHAR 7) (*QTDCHAR 10) ...
