NAME

       stilts-tjoin - Joins multiple tables side-to-side

SYNOPSIS

       stilts tjoin [nin=<count>] [ifmtN=<in-format>] [inN=<tableN>] [icmdN=<cmds>] [ocmd=<cmds>]
                    [omode=out|meta|stats|count|cgi|discard|topcat|samp|tosql|gui] [out=<out-
                    table>] [ofmt=<out-format>] [fixcols=none|dups|all] [suffixN=<label>]

DESCRIPTION

       tjoin  performs a trivial side-by-side join of multiple tables. The N'th row of the output
       table consists of the N'th row of the first input table, followed by the N'th row  of  the
       second  input  table,  ... and so on. It is suitable if you want to amalgamate two or more
       tables whose row orderings correspond exactly to each other.

       For the (more usual) case in which the rows of the tables to be joined are not already  in
       the right order, use one of the crossmatching commands.

OPTIONS

       nin=<count>
              The number of input tables for this task. For each of the input tables N there will
              be associated parameters ifmtN, inN and icmdN.

       ifmtN=<in-format>
              Specifies the format of input table #N as specified by  parameter  inN.  The  known
              formats  are  listed in SUN/256. This flag can be used if you know what format your
              table is in. If it has the special value (auto) (the default), then an attempt will
              be made to detect the format of the table automatically. This cannot always be done
              correctly however, in which case the program will exit  with  an  error  explaining
              which formats were attempted.

       inN=<tableN>
              The location of input table #N. This may take one of the following forms:

                * A filename.

                * A URL.

                * The  special  value  "-", meaning standard input. In this case the input format
                  must be given explicitly using the ifmtN parameter. Note that not  all  formats
                  can be streamed in this way.

                * A  system  command  line  with  either  a  "<" character at the start, or a "|"
                  character at the end ("<syscmd" or "syscmd|"). This executes the given pipeline
                  and  reads  from its standard output. This will probably only work on unix-like
                  systems.
               In any case, compressed data in one of the supported  compression  formats  (gzip,
              Unix compress or bzip2) will be decompressed transparently.

       icmdN=<cmds>
              Specifies  processing  to  be performed on input table #N as specified by parameter
              inN, before any other processing has taken place. The value of  this  parameter  is
              one or more of the filter commands described in SUN/256. If more than one is given,
              they must be separated  by  semicolon  characters  (";").  This  parameter  can  be
              repeated  multiple  times on the same command line to build up a list of processing
              steps. The sequence of commands given in this way defines the  processing  pipeline
              which is performed on the table.

              Commands may alteratively be supplied in an external file, by using the indirection
              character '@'. Thus a value of "@filename" causes the file filename to be read  for
              a  list of filter commands to execute. The commands in the file may be separated by
              newline characters and/or semicolons, and lines which are blank or which start with
              a '#' character are ignored.

       ocmd=<cmds>
              Specifies  processing  to  be  performed  on  the  output  table,  after  all other
              processing has taken place. The value of this parameter  is  one  or  more  of  the
              filter  commands  described  in  SUN/256.  If  more than one is given, they must be
              separated by semicolon characters (";"). This parameter can  be  repeated  multiple
              times on the same command line to build up a list of processing steps. The sequence
              of commands given in this way defines the processing pipeline which is performed on
              the table.

              Commands may alteratively be supplied in an external file, by using the indirection
              character '@'. Thus a value of "@filename" causes the file filename to be read  for
              a  list of filter commands to execute. The commands in the file may be separated by
              newline characters and/or semicolons, and lines which are blank or which start with
              a '#' character are ignored.

       omode=out|meta|stats|count|cgi|discard|topcat|samp|tosql|gui
              The  mode  in which the result table will be output. The default mode is out, which
              means that the result will be written as a new  table  to  disk  or  elsewhere,  as
              determined  by the out and ofmt parameters. However, there are other possibilities,
              which correspond to uses to which a table can be put other than outputting it, such
              as  displaying  metadata,  calculating  statistics, or populating a table in an SQL
              database. For some values of this parameter,  additional  parameters  (<mode-args>)
              are required to determine the exact behaviour.

              Possible values are

                * out

                * meta

                * stats

                * count

                * cgi

                * discard

                * topcat

                * samp

                * tosql

                * gui
               Use the help=omode flag or see SUN/256 for more information.

       out=<out-table>
              The  location of the output table. This is usually a filename to write to. If it is
              equal to the special value "-" (the default) the output table will  be  written  to
              standard output.

              This parameter must only be given if omode has its default value of "out".

       ofmt=<out-format>
              Specifies  the format in which the output table will be written (one of the ones in
              SUN/256 - matching is case-insensitive and you can use just the first few letters).
              If  it  has the special value "(auto)" (the default), then the output filename will
              be examined to try to guess what sort of file is required usually by looking at the
              extension. If it's not obvious from the filename what output format is intended, an
              error will result.

              This parameter must only be given if omode has its default value of "out".

       fixcols=none|dups|all
              Determines how input columns are renamed  before  use  in  the  output  table.  The
              choices are:

                * none: columns are not renamed

                * dups:  columns which would otherwise have duplicate names in the output will be
                  renamed to indicate which table they came from

                * all: all columns will be renamed to indicate which table they came from
               If columns are renamed, the new ones are determined by suffix* parameters.

       suffixN=<label>
              If the fixcols parameter is set so that input columns  are  renamed  for  insertion
              into the output table, this parameter determines how the renaming is done. It gives
              a suffix which is appended to all renamed columns from table N.
