Biztalk Flat File Transform multiple unbound records causing Unexpected Data Error -

-

i trying import flat file sql database via biztalk 2006 r2. input file has layout follows each line separated cr/lf trailing cr/lf @ end:

00(29characters after)  <=== header 07(997characters after) <=== record type 07 (unbounded, 0-?? possible records) 08(86characters after)  <=== record type 08 (unbounded, 0-?? possible records) 09(89characters after)  <=== record type 09 (unbounded, 0-?? possible records) 10(94characters after)  <=== record type 10 (unbounded, 0-?? possible records) 16(35characters after)  <=== group footer 17(30characters after)  <=== file footer

anyway, ran flat file wizard, , created xml, "repeating records" selected, set min , max occurrences of 07,08,09 , 10. changed min 0 , max unbounded. now, no matter do, unexpected data found while looking for:'\r\n' error when validating. i've tried setting default child order postfix , child order of root infix , postfix both. nothing seems help.

creating schema scratch

i think using flat file schema wizard moderately complex structures, one, not worth trouble. suggestion, think overall structure, , provide outline using schema editor.

so, example calls schema has following structure :

a single header record typed 00, followed sequence of records typed 07, 08, 09and 10 respectively. each typed record structure in , of itself, contains number of repeating records. finally, structure ends single grouptrailer record typed 16, followed overall trailerrecord, typed 17.

this maps nicely following schema in biztalk :

flat file schema structure

now, need tweak various properties of nodes in order instruct flat file disassembler how parse incoming messages.

root record

the root record there group various child records , required structured xml document. however, not participate in parsing of incoming structure.

therefore, should set child delimiter type none.

header, grouptrailer , trailer records

the header, grouptrailer , trailer records each occur single time, leave min occurs , max occurs properties default value of 1.

furthermore, each of these records identified appropriate tag identifier of 00, 16 , 17 respectively.

finally, records each end trailing cr/lf pair or characters. therefore, set child delimiter type properties hexadecimal, , child order properties postfix.

type07, type08, type09 , type10 structures

this tricky part.

one way @ structures contain repeating records, each delimited trailing cr/lf. however, structures appear once.

another important point need single cr/lf pair delimiter both structures , child records. so, settings of child delimiter type properties should reflect that.

for type07, type08, type09 , type10 records, leave default settings. is, set child delimiter type property none , child order property conditional default. in particular, there no tag identifier set these records.

type07_record, type08_record, type09_record , type10_record structures

however, type07_record, type08_record, type09_record , type10_record set occur multiple times. set min occurs properties 0 , max occurs properties unbounded.

additionnaly, each repeating record ends trailing cr/lf pair. therefore, set child delimiter type properties hexadecimal, child order properties postfix , child delimiter properties 0x0d 0x0a.

reference

for reference, resulting settings :

  • root : delimited, none, conditional default.

  • header : delimited, hexadecimal, 0x0d 0x0a, postfix, tag identifier 00.

  • <sequence> : (optional), minoccurs: 1, maxoccurs: 1

  • type07 : delimited, none, conditional default.

  • type07_record : delimited, hexadecimal, 0x0d 0x0a, postfix, tag identifier 07.

  • type08 : delimited, none, conditional default.

  • type08_record : delimited, hexadecimal, 0x0d 0x0a, postfix, tag identifier 08.

  • type09 : delimited, none, conditional default.

  • type09_record : delimited, hexadecimal, 0x0d 0x0a, postfix, tag identifier 09.

  • type10 : delimited, none, conditional default.

  • type10_record : delimited, hexadecimal, 0x0d 0x0a, postfix, tag identifier 10.

  • grouptrailer : delimited, hexadecimal, 0x0d 0x0a, postfix, tag identifier 16.

  • trailer : delimited, hexadecimal, 0x0d 0x0a, postfix, tag identifier 17.

php - Mysql PK and FK char(36) vs int(10) -

-
i have read mysql can handle indexes , searches better if tables keys integers rather char(36) uuid's. is worth converting int(10)? note: use 1 server , have have plans use multiple databases concurrently therefore removing 1 of big reasons using uuid. our tables innodb if makes difference. thanks in advance. usually rdbms can handle integer keys pk more efficient, other datatypes. reason how build index column, yes: long dont require string (or other typed) keys, should use integers. however: char(36) , int(10) far away being equal, because int(10) much smaller, char(36). dont know, if require many different keys, should keep in mind. update, complete last paragraph: int(10) 32-bit, char(36) 36 - ^byte^ (= 288-bit). not mean, int consumes less space, means, char(36) has 4 times more different keys.
