Initialize the DB

buildCondition(condDict=None, older=None, newer=None, timeStamp=None, orderAttribute=None, limit=False, greater=None, smaller=None, offset=None)

Build SQL condition statement from provided condDict and other extra check on a specified time stamp. The conditions dictionary specifies for each attribute one or a List of possible values greater and smaller are dictionaries in which the keys are the names of the fields, that are requested to be >= or < than the corresponding value. For compatibility with current usage it uses Exceptions to exit in case of invalid arguments

countEntries(table, condDict, older=None, newer=None, timeStamp=None, connection=False, greater=None, smaller=None)

Count the number of entries wit the given conditions

deleteEntries(tableName, condDict=None, limit=False, conn=None, older=None, newer=None, timeStamp=None, orderAttribute=None, greater=None, smaller=None)

Delete rows from “tableName” with N records can match the condition if limit is not False, the given limit is set String type values will be appropriately escaped, they can be single values or lists of values.

executeStoredProcedure(packageName, parameters, outputIds)
executeStoredProcedureWithCursor(packageName, parameters)
getCSOption(optionName, defaultValue=None)
getComponentsStatus(conditionDict={})

Get the status of the defined components in the CS compared to the ones that are known in the DB

getCounters(table, attrList, condDict, older=None, newer=None, timeStamp=None, connection=False, greater=None, smaller=None)

Count the number of records on each distinct combination of AttrList, selected with condition defined by condDict and time stamps

getDistinctAttributeValues(table, attribute, condDict=None, older=None, newer=None, timeStamp=None, connection=False, greater=None, smaller=None)

Get distinct values of a table attribute under specified conditions

getFields(tableName, outFields=None, condDict=None, limit=False, conn=None, older=None, newer=None, timeStamp=None, orderAttribute=None, greater=None, smaller=None)

Select “outFields” from “tableName” with condDict N records can match the condition return S_OK( tuple(Field,Value) ) if outFields is None all fields in “tableName” are returned if limit is not False, the given limit is set inValues are properly escaped using the _escape_string method, they can be single values or lists of values.

getOptionalFields()
heartbeat(compDict)

Update heartbeat

insertFields(tableName, inFields=None, inValues=None, conn=None, inDict=None)

Insert a new row in “tableName” assigning the values “inValues” to the fields “inFields”. String type values will be appropriately escaped.

registerComponent(compDict, shallow=False)

Register a new component in the DB. If it’s already registered return id

transactionCommit()
transactionRollback()
transactionStart()
updateFields(tableName, updateFields=None, updateValues=None, condDict=None, limit=False, conn=None, updateDict=None, older=None, newer=None, timeStamp=None, orderAttribute=None, greater=None, smaller=None)

Update “updateFields” from “tableName” with “updateValues”. updateDict alternative way to provide the updateFields and updateValues N records can match the condition return S_OK( number of updated rows ) if limit is not False, the given limit is set String type values will be appropriately escaped.
