Question

I have a shell script (.sh) that works in Unix but I’d like to convert it into a Windows batch file (.bat):

cat >flog.ctl <<_EOF
LOAD DATA
INFILE '$1.log' "str ';'"
APPEND INTO TABLE flog
fields terminated by '=' TRAILING NULLCOLS
(
filename constant '$1'
,num  char
,data char
)
_EOF

sqlldr <username>/<password>@<instance> control=flog.ctl data=$1.log

I’m not too knowledgable on batch files but if an answer is some hints rather than a complete solution then I’m sure I’ll muddle through. This is to help with an answer to another question here.

Answer 1

Windows batch files do not support inlining data this way. You’ll have to

ECHO firstLine > flog.ctl
ECHO additionalLine >> flog.ctl

Windows batch files denote variables in ECHO statements using % signs, i.e. %1%.

So you’re resulting file would be something like:

@ECHO OFF
ECHO LOAD DATA > flog.ctl
ECHO INFILE '%1%.log' "str ';'" >> flog.ctl
ECHO APPEND INTO TABLE flog >> flog.ctl
ECHO fields terminated by '=' TRAILING NULLCOLS >> flog.ctl
ECHO ( >> flog.ctl
ECHO filename constant '%1%' >> flog.ctl
ECHO ,num  char >> flog.ctl
ECHO ,data char >> flog.ctl
ECHO ) >> flog.ctl

sqlldr <username>/<password>@<instance> control=flog.ctl data=%1%.log
