ssis - Handling Inconsistent Delimiters in Flat File Source on ForeachLoop Container -



ssis - Handling Inconsistent Delimiters in Flat File Source on ForeachLoop Container -

i'm trying handle inconsistent delimiters in 'n flat file source contained in info flow task running in foreach loop container in ssis.

i have several files in folder varying names 1 consistent identifier e.g. file23998723.txt file39872397.txt file29387234.txt etc., etc.

these files, standard should tab delimited, every user missed cleaning file , delimited , or ; etc., causes bundle import fail.

is there easy approach me follow dynamically alter delimiter or test delimiter beforehand?

i managed handle script task, thanks!

basically added script task foreach loop container executes before dataflow task.

i send file name through variable:

i added next namespaces script:

using system.io; using runtimewrapper = microsoft.sqlserver.dts.runtime.wrapper;

and script looks this:

public void main() { if (!string.isnullorempty(dts.variables["sfilename"].value.tostring())) { streamreader file = new streamreader(dts.variables["sfilename"].value.tostring()); if (file != null) { string headrowdelimiter = ""; string coldelimiter = ""; string info = ""; while (file.peek() >= -1) { char[] c = new char[500]; file.read(c, 0, c.length); info = string.join("", c); if (!string.isnullorempty(data)) { //set row delimiters if (data.contains("\r\n")) { headrowdelimiter = "\r\n"; } else if (data.contains("\r")) { headrowdelimiter = "\r"; } else if (data.contains("\n")) { headrowdelimiter = "\n"; } else if (data.contains("\0")) { headrowdelimiter = "\0"; } //set column delimiters if (data.contains("\t")) { coldelimiter = "\t"; } else if (data.contains(";")) { coldelimiter = ";"; } else if (data.contains(",")) { coldelimiter = ","; } else if (data.contains(":")) { coldelimiter = ":"; } else if (data.contains("|")) { coldelimiter = "|"; } else if (data.contains("\0")) { coldelimiter = "\0"; } } break; } file.close(); runtimewrapper.idtsconnectionmanagerflatfile100 flatfileconnection = dts.connections["flatfileconnection"].innerobject runtimewrapper.idtsconnectionmanagerflatfile100; if (flatfileconnection != null) { flatfileconnection.headerrowdelimiter = headrowdelimiter; flatfileconnection.rowdelimiter = headrowdelimiter; flatfileconnection.headerrowstoskip = 0; flatfileconnection.columns[0].columndelimiter = coldelimiter; } dts.taskresult = (int)scriptresults.success; } } }

assembly - What is the addressing mode for ld, add, and rjmp instructions? - hey guys know ldi (load immediate) addressing mode set immediate , st instruction addressing mode set index. however, have no thought others curious are! thanks :) the addressing modes explained in instruction set, in first few pages. in table of instructions see operands instruction determine addressing mode. mode indicated arguments assembly instruction. for example, ld had several different ways of operating, depending on arguments. 1 of them ld rd,x d number of register, such ld r3,x . ld r3,-z else (although both indirect addressing). rjmp k relative addressing, jumping pc + k + 1. add rr,rd direct register addressing. result contained in rd. assembly avr instructions
