72 "fits2sql - Fills the data from a fits file into a database\n"
73 "\n"
74 "For convenience, this documentation uses the extended version of the options, "
75 "refer to the output below to get the abbreviations.\n"
76 "\n"
77 "This is a general purpose tool to fill the contents of a fite file into a database.\n"
78 "\n"
79 "Each fits file contians several table, so called extenbsions. Each tables has "
80 "a number of columns compilsed from basic data types. The default extension to "
81 "read from is the first one on the file but the name can be overwritten using "
82 "--extension. The default table name to fill the data into is identical to "
83 "the extension name. It can be overwritten using --table.\n"
84 "\n"
85 "The name of each column to which data is filled is obtained from "
86 "the fits column names. The column names can be checked using --print-columns. "
87 "Sometimes these names might not be convenient. To allow to simplify or replace "
88 "column names, regular expressions (using boost's regex) can be defined to change "
89 "the names. Note that these regular expressions are applied one by one on each "
90 "columns's name. A valid expression could "
91 "be:\n"
92 " --map=MHillas\\.f/\n"
93 "which would remove all occurances of 'MHillas.f'. This option can be used more than "
94 "once. They are applied in sequence. A single match does not stop the sequence.\n"
95 "\n"
96 "Sometimes it might also be convenient to skip a column. This can be done with "
97 "the --ignore resource. If the given regular expresion yields a match, the "
98 "column will be ignored. Note that the regular expression works on the raw-name "
99 "of the column not the readily mapped SQL column names. Example:\n"
100 " --ignore=ThetaSq\\..*\n"
101 "will skip all leaved which start with 'ThetaSq.'. This option can be used"
102 "more than once.\n"
103 "\n"
104 "The data type of each column is kept as close as possible to the columns' data "
105 "types. If for some reason this is not wanted, the data type of the SQL column "
106 "can be overwritten with --sql-type sql-column/sql-ytpe, for example:\n"
107 " --sql-type=FileId/UNSIGNED INT\n"
108 "while the first argument of the name of the SQL column to which the data type "
109 "should be applied. The second column is the basic SQL data type. The option can "
110 "be given more than once.\n"
111 "\n"
112 "Database interaction:\n"
113 "\n"
114 "To drop an existing table, --drop can be used.\n"
115 "\n"
116 "To create a table according to theSQL column names and data types, --create "
117 "can be used. The query used can be printed with --print-create even --create "
118 "has not been specified.\n"
119 "\n"
120 "To choose the columns which should become primary keys, use --primary, "
121 "for example:\n"
122 " --primary=col1\n"
123 "To define more than one column as primary key, the option can be given more than "
124 "once. Note that the combination of these columns must be unique.\n"
125 "\n"
126 "All columns are created as NOT NULL as default. To force a database engine "
127 "and/or a storage format, use --engine and --rot-format.\n"
128 "\n"
129 "Usually, the INSERT query would fail if the PRIMARY key exists already. "
130 "This can be avoided using the 'ON DUPLICATE KEY UPDATE' directive. With the "
131 "--duplicate, you can specify what should be updated in case of a duplicate key. "
132 "To keep the row untouched, you can just update the primary key "
133 "with the identical primary key, e.g. --duplicate='MyPrimary=VALUES(MyPrimary)'. "
134 "The --duplicate resource can be specified more than once to add more expressions "
135 "to the assignment_list. For more details, see the MySQL manual.\n"
136 "\n"
137 "Another possibility is to add the IGNORE keyword to the INSERT query by "
138 "--ignore-errors, which essentially ignores all errors and turns them into "
139 "warnings which are printed after the query succeeded.\n"
140 "\n"
141 "For debugging purpose, or to just create or drop a table, the final insert "
142 "query can be skipped using --no-insert. Note that for performance reason, "
143 "all data is collected in memory and a single INSERT query is issued at the "
144 "end.\n"
145 "\n"
146 "Using a higher verbosity level (-v), an overview of the written columns or all "
147 "processed leaves is printed depending on the verbosity level. The output looks "
148 "like the following\n"
149 " Leaf name [root data type] (SQL name)\n"
150 "for example\n"
151 " MTime.fTime.fMilliSec [Long64_t] (MilliSec)\n"
152 "which means that the leaf MTime.fTime.fMilliSec is detected to be a Long64_t "
153 "which is filled into a column called MilliSec. Leaves with non basic data types "
154 "are ignored automatically and are marked as (-n/a-). User ignored columnd "
155 "are marked as (-ignored-).\n"
156 "\n"
157 "A constant value for the given file can be inserted by using the --const directive. "
158 "For example --const.mycolumn=42 would insert 42 into a column called mycolumn. "
159 "The column is created as INT UNSIGNED as default which can be altered by "
160 "--sql-type. A special case is a value of the form `/regex/format/`. Here, the given "
161 "regular expression is applied to the filename and it is newly formated with "
162 "the new format string. For details on how backreferences work, see for example "
163 "the man-page of the sed utility.\n"
164 "\n"
165 "Usually the previously defined constant values are helpful to create an index "
166 "which relates unambiguously the inserted data to the file. It might be useful "
167 "to delete all data which belongs to this particular file before new data is "
168 "entered. This can be achieved with the `--delete` directive. It deletes all "
169 "data from the table before inserting new data which fulfills the condition "
170 "defined by the `--const` directives.\n"
171 "\n"
172 "The constant values can also be used for a conditional execution (--conditional). "
173 "If any row with the given constant values are found, the execution is stopped "
174 "(note that this happend after the table drop/create but before the delete/insert.\n"
175 "\n"
176 "To ensure efficient access for a conditonal execution, it makes sense to have "
177 "an index created for those columns. This can be done during table creation "
178 "with the --index option.\n"
179 "\n"
180 "To create the index as a UNIQUE INDEX, you can use the --unique option which "
181 "implies --index.\n"
182 "\n"
183 "If a query failed, the query is printed to stderr together with the error message. "
184 "For the main INSERT query, this is only true if the verbosity level is at least 2 "
185 "or the query has less than 80*25 bytes.\n"
186 "\n"
187 "In case of success, 0 is returned, a value>0 otherwise.\n"
