| 35 <h2>DESCRIPTION</h2> | |
| 36 <p>Export table data from database SchemaName(s) into CSV/TSV text files. Use <strong>-n --numoutfiles</strong> | |
| 37 option to control the number of text files generated for a database schema.</p> | |
| 38 <p> | |
| 39 </p> | |
| 40 <h2>OPTIONS</h2> | |
| 41 <dl> | |
| 42 <dt><strong><strong>-d, --dbdriver</strong> <em>mysql | Oracle | Postgres or Pg</em></strong></dt> | |
| 43 <dd> | |
| 44 <p>Database driver name. Possible values: <em>mysql, Oracle, Postgres or Pg</em>. Default: <em>MySQL</em> or value of | |
| 45 environment variable DBI_DRIVER. This script has only been tested with MySQL, Oracle | |
| 46 and PostgreSQL drivers.</p> | |
| 47 </dd> | |
| 48 <dt><strong><strong>--dbhost </strong> <em>hostname</em></strong></dt> | |
| 49 <dd> | |
| 50 <p>Database host name. Default: <em>127.0.0.1</em> for both MySQL and Oracle. For remote | |
| 51 databases, specify complete remote host domain: <em>dbhostname.org</em> or something | |
| 52 like it.</p> | |
| 53 </dd> | |
| 54 <dt><strong><strong>--dbname</strong> <em>databasename</em></strong></dt> | |
| 55 <dd> | |
| 56 <p>Database name. Default: mysql for MySQL, postgres for PostgreSQL and none for Oracle. | |
| 57 For connecting to local/remote Oracle databases, this value can be left undefined assuming | |
| 58 <strong>--dbhost</strong> is correctly specified.</p> | |
| 59 </dd> | |
| 60 <dt><strong><strong>--dbpassword</strong> <em>password</em></strong></dt> | |
| 61 <dd> | |
| 62 <p>Database user password. Default: <em>none</em> and value of environment variable DBI_PASS | |
| 63 is used for connecting to database.</p> | |
| 64 </dd> | |
| 65 <dt><strong><strong>--dbusername</strong> <em>username</em></strong></dt> | |
| 66 <dd> | |
| 67 <p>Database user name. Default: <em>none</em> and value of environment variable DBI_USER is | |
| 68 used for connecting to database.</p> | |
| 69 </dd> | |
| 70 <dt><strong><strong>--exportdatalabels</strong> <em>yes | no</em></strong></dt> | |
| 71 <dd> | |
| 72 <p>This option is mode specific and controls exporting of column data labels during | |
| 73 exportdata mode. Possible values: <em>yes or no</em>. Default: <em>yes</em>.</p> | |
| 74 </dd> | |
| 75 <dt><strong><strong>--exportlobs</strong> <em>yes | no</em></strong></dt> | |
| 76 <dd> | |
| 77 <p>This option is mode specific and controls exporting of CLOB/BLOB or BYTEA data columns during | |
| 78 exportdata mode. Possible values: <em>yes or no</em>. Default: <em>no</em>.</p> | |
| 79 </dd> | |
| 80 <dt><strong><strong>-h, --help</strong></strong></dt> | |
| 81 <dd> | |
| 82 <p>Print this help message.</p> | |
| 83 </dd> | |
| 84 <dt><strong><strong>-m, --mode</strong> <em>exportdata | describetable</em></strong></dt> | |
| 85 <dd> | |
| 86 <p>Data selection criterion from database. Possible values: <em>exportdata or describetable</em>. | |
| 87 Default value: <em>exportdata</em>.</p> | |
| 88 </dd> | |
| 89 <dt><strong><strong>-n, --numoutfilesmode</strong> <em>single | multiple</em></strong></dt> | |
| 90 <dd> | |
| 91 <p>Number of CSV/TSV output files to generate: combine output into one file or generate | |
| 92 a different file for each table in a schema. Possible values: <em>single or multiple</em>. Default: | |
| 93 <em>single</em>.</p> | |
| 94 <p>In a single output file, data for different tables is separated by a blank line.</p> | |
| 95 <p>Single outfile option in <em>exportdata</em> mode is quite useful for exporting data from all tables | |
| 96 in specifed schemas to one file which can be used for migrating data to another database | |
| 97 or simply provide a backup of data; during <em>describetable</em> mode, it provides a means to | |
| 98 collect information about columns of all schema tables which can help in creation of these | |
| 99 tables on a different database server.</p> | |
| 100 </dd> | |
| 101 <dt><strong><strong>-o, --overwrite</strong></strong></dt> | |
| 102 <dd> | |
| 103 <p>Overwrite existing files.</p> | |
| 104 </dd> | |
| 105 <dt><strong><strong>--outdelim</strong> <em>comma | tab | semicolon</em></strong></dt> | |
| 106 <dd> | |
| 107 <p>Output text file delimiter. Possible values: <em>comma, tab, or semicolon</em>. | |
| 108 Default value: <em>comma</em></p> | |

| 112 <p>Put quotes around column values in output text file. Possible values: <em>yes or | |
| 113 no</em>. Default value: <em>yes</em>.</p> | |
| 114 </dd> | |
| 115 <dt><strong><strong>-r, --root</strong> <em>rootname</em></strong></dt> | |
| 116 <dd> | |
| 117 <p>New file name is generated using the root:<Root>.<Ext> and <Root><TableName>.<Ext> | |
| 118 for <em>single</em> and <em>multiple</em> <strong>-n --numoutfiles</strong> option values. Default file name for | |
| 119 <em>single</em> <strong>-n --numoutfiles</strong> option value: <Mode>SchemaTables.<Ext>. Default file | |
| 120 names for <em>multiple</em> <strong>-n --numoutfiles</strong> value: <Mode><SchemaName><TableName>.<Ext>. | |
| 121 Based on <strong>-m --mode</strong> option, <em>Export</em> or <em>Describe</em> <Mode> value is used. The csv and tsv | |
| 122 <Ext> values are used for comma/semicolon, and tab delimited text files respectively. This option is | |
| 123 ignored for multiple input schema names.</p> | |
| 124 </dd> | |
| 125 <dt><strong><strong>--replacenullstr</strong> <em>string</em></strong></dt> | |
| 126 <dd> | |
| 127 <p>Replace NULL or undefined row values with specified value. Default: <em>none</em>.</p> | |
| 128 <p>For importing output text files into MySQL database using "load data local infile '<tablename>.tsv' | |
| 129 into table <tablename>" command, use <em>--raplacenullstr "NULL"</em> in conjunction with <em>--exportdatalabels no</em>, | |
| 130 <em>--quote no</em>, and <em>--outdelim tab</em> options: it'll generate files for direct import into MySQL assuming | |
| 131 tables already exists.</p> | |
| 132 </dd> | |
| 133 <dt><strong><strong>-w --workingdir</strong> <em>dirname</em></strong></dt> | |
| 134 <dd> | |
